How to Butcher a Whole Bison Complete Guide

 

All Primal Cuts for Bison

How to Butcher a Whole Bison Complete Guide covers the one large animal that punishes butchers for treating it like beef. Bison fabricates along the same seams as a steer and yields most of the same named cuts, but it is a fundamentally leaner animal, and that single difference changes trimming, grinding, rendering, aging and every cooking temperature that follows. According to USDA data, 100 grams of raw separable lean bison carries 1.8 grams of fat against 24 grams for USDA Choice beef. That is not a marginal difference. It is the whole guide.

Carcass size is closer to beef than most people expect. USDA-reported average hot carcass weight for young bison under 30 months of age has run in the range of 588 to 623 lbs in recent years, according to South Dakota State University Extension analysis of federal market reports. Mature bulls run considerably heavier. As with beef, modern fabrication relies on seam butchery: tracing the natural connective tissue boundaries between muscle groups with a flexible boning knife rather than sawing through them.

This step-by-step guide is written for beginners who have either bought a bison quarter or taken one in the field. You will learn how to set up a sanitary cutting space, work the forequarter and hindquarter, handle the hump primal that beef does not have, seam out the round, build a grind that actually works on meat this lean, and cook every cut without drying it out.

Wine Drop Cookery focuses on connecting artisan ingredient sourcing with precise preparation. Bison rewards precision more than beef does, because the fat margin that forgives a mistake on a ribeye is not there.

Whole Animal Principle: Responsible bison fabrication honors the animal through complete utilization, from hump roast and tenderloin to shank, marrow bones, and the lean trim that becomes the bulk of what goes in the freezer.

Beginner Fundamentals: Understanding Bison Fabrication

Before making the first incision, it is worth understanding exactly how bison differs from the beef carcass most butchery instruction is written around. The skeleton and the seams are broadly familiar. The tissue between them is not.

1. Why Bison Is Not Beef: The Leanness Problem

Every decision in this guide traces back to one fact. USDA figures put raw separable lean bison at 109 calories and 1.8 grams of fat per 100 grams, against 291 calories and 24 grams of fat for USDA Choice beef. Bison carries roughly a thirteenth of the fat by that measure.

That fat is also distributed differently. Beef quality grading is built around intramuscular marbling, the white flecks inside the muscle that melt during cooking and baste the fibers from within. Bison carries very little marbling. What fat it does have sits as an external cap and around the organs.

Four consequences follow, and they run through every section below:

  • Trimming is less forgiving. There is no interior fat reserve to compensate for an over-trimmed exterior.
  • A straight bison grind will not make a burger. Ground lean at these fat levels produces a dry, crumbling patty. Fat has to be added deliberately.
  • Rendering yields little. A beef quarter gives back meaningful tallow. A bison quarter gives back a fraction of it.
  • Cooking windows are narrow. Without melting intramuscular fat, the gap between correctly cooked and ruined is smaller and arrives faster.

2. What Is Seam Butchery and Why It Matters More Here

Seam butchery is the method of separating meat along natural connective tissue boundaries rather than sawing straight through muscle and bone. Each muscle sits inside a thin sheath of connective tissue. Inserting the tip of a flexible boning knife into that division allows the blade to glide along the seam and release whole, clean muscle groups.

On bison this matters more than on beef, for a practical reason: the seams are easier to see. With less intramuscular fat obscuring the boundaries, the white connective tissue lines read clearly against dark muscle. Beginners frequently find bison easier to seam out than beef for exactly this reason, even though the animal is harder to cook.

3. The 5 Golden Rules for Beginner Bison Butchers

  • Keep Meat Chilled (34-38°F): Never attempt to butcher warm meat. Cold fat stays firm and trims cleanly, and cold muscle holds its shape under the blade.
  • Slice With Smooth Draw Strokes: Avoid short sawing motions. Use the full length of the blade in long continuous pulls to leave smooth faces on roasts and steaks.
  • Follow Natural Muscle Seams: Let the anatomy lead. Heavy resistance means the blade is in bone or crossing a muscle rather than following a seam.
  • Respect Grain Direction: Cut steaks across the grain to shorten muscle fibers. On a lean animal this contributes more to perceived tenderness than it does on a well-marbled one.
  • Leave More Fat Than Instinct Suggests: This rule is specific to bison. The external fat cap is most of the fat the animal has. Trimming it to the standard beef finish removes protection the meat cannot spare.

4. Realistic Yield Expectations

USDA-reported average hot carcass weights for young bison under 30 months have run between roughly 588 and 623 lbs in recent years, per South Dakota State University Extension analysis. Mature bulls are substantially heavier and are usually processed differently.

Expect the yield mix to skew toward grind compared with beef, because there is less fat to trim away and more lean trim left over from the seam work.

[CHEF: dressing percentage, live-to-hanging conversion, and your own take-home percentages by category belong here. I could not verify bison-specific dressing figures from a source I would publish, and beef percentages do not transfer. Your numbers from actual animals are better than anything I would find.]

Essential USDA Safety and Sanitation Guide for Bison

1. Voluntary Inspection: What It Means for You

This is the regulatory difference that surprises people, and it is worth stating plainly. Bison is not subject to mandatory federal inspection the way beef, pork and lamb are. USDA Food Safety and Inspection Service states that bison may be inspected under voluntary federal inspection or under FDA-equivalent inspection.

Practically, that means the inspection legend on a bison carcass is a choice the producer made and paid for, rather than a legal requirement. It does not imply the meat is unsafe. It does mean the responsibility for verifying the source sits further onto the buyer than it does with beef, and that field-harvested animals carry no inspection at all.

2. Temperature Control: The 40°F (4°C) Rule

Bacterial growth accelerates rapidly in the danger zone between 40°F (4°C) and 140°F (60°C).

  • Chill hanging carcasses below 40°F (4°C) as rapidly as facilities allow.
  • Maintain the cutting room at or below 50°F (10°C) during processing.
  • Work one primal at a time and hold the remainder in cold storage at 34-36°F (1-2°C).
  • USDA guidance for fresh bison in domestic refrigeration is 40°F or below, used within 3 to 5 days or frozen.

3. Field Harvest and Cold Chain

A significant share of bison is taken in the field rather than at a plant, and field care determines the result far more than knife work does. The carcass is large, insulated, and slow to shed heat. Getting core temperature down is the first priority and the one most often mishandled.

[CHEF: field dressing sequence, quartering in the field, and your cooling timeline recommendations belong here. This is judgement from experience rather than something to research.]

4. Cross-Contamination Prevention and Surface Sanitation

Scrub all cutting tables, meat hooks, bone saws, and cutlery before and after fabrication using hot soapy water at a minimum of 110°F, followed by a food-safe sanitizing solution such as one tablespoon of unscented household bleach per gallon of water. Use color-coded non-porous HDPE cutting boards dedicated to raw meat.

5. Safe Internal Cooking Temperatures for Bison

USDA Food Safety and Inspection Service gives the following minimums for bison:

  • Steaks and Roasts: 145°F (63°C), with a 3-minute rest.
  • Ground Bison: 160°F (71°C), because surface bacteria are distributed through the meat during grinding.

Many cooks take whole-muscle bison steaks to medium rare at 130-135°F, as they would with beef. That is a personal risk decision rather than a USDA recommendation, and it is worth stating that the leanness of the animal makes overshooting the target far more punishing than undershooting it. A Digital Meat Thermometer handles steaks, and a Digital Meat Thermometer with Long Probe reaches the center of a hump roast or a standing rib without bottoming out on bone.

Beginner Equipment Checklist

The tool list is the same as beef. The animal is large, the bones are heavy, and nothing about bison calls for specialist equipment.

1. The Core Knives Every Beginner Butcher Needs

  • 6-inch Stiff Boning Knife: The primary blade for separating joints, stripping meat from bone, and trimming.
  • 10 or 12-inch Cimeter Knife: A long curved blade for slicing large primals and cutting uniform steaks in one pulling motion.
  • 8-inch Breaking Knife: Stiff and sturdy, for dividing quarters into subprimals.
  • 3.5-inch Paring Knife: Detail trimming and membrane removal.

Four knives, and every one of them earns its place. Beginners routinely buy a fifteen-piece block and use three of the knives in it. Buy fewer and buy better. The Handmade Damascus Western Chef Knife Set covers the boning and paring roles in forged steel that holds an edge through a full quarter, and the 5-Piece Chef Knife Set with Leather Roll keeps the kit together for anyone processing away from a home kitchen, which describes most field-harvested bison. The rest of the professional knife sets are hand forged and full tang.

Silverskin removal takes longer on bison than on beef. With little intramuscular fat softening the picture, the membrane is more prominent and more of it needs to come off. A sharp paring knife is not optional here.

2. Meat Saws, Hanging Hooks, and Sanitary Prep Tables

A 16 to 22-inch hand meat saw with a stainless blade cuts cleanly through chine bones and spinal columns. The elongated dorsal spinal processes that form the hump are heavier bone than the equivalent region on beef, so a sharp saw blade matters more. Stainless meat hooks and a gambrel allow the carcass to be suspended, which is not optional on an animal this size.

Bison subprimals run large. A whole strip loin or top round runs past the edge of a standard cutting surface, which is how meat ends up on the counter. The Two-Tone XL Cutting Board at 18 by 12 inches gives room to portion steaks off a full loin in one pass.

3. Grinders, Added Fat, and Vacuum Sealing

Grind is a larger share of a bison harvest than a beef one, so the grinder is a core purchase rather than an accessory. A 0.75 to 1.0 HP electric grinder processes chuck and round trim without stalling. The Electric Meat Grinder works through lean trim steadily, and the 3-in-1 Stand Mixer with Meat Grinder handles the grind and the mix on one machine where counter space is limited. The mixing function matters more on bison than beef, because added fat has to be distributed evenly through lean trim that will not do it on its own.

A chamber or heavy-duty suction vacuum sealer using 4-mil bags protects packaged meat against freezer burn. Lean meat is more vulnerable to freezer burn than fatty meat, so sealing quality matters more here.

Bison Anatomy Map: Primal Cuts Explained

Primal Steak Cuts

A bison carcass divides into broadly the same primal regions as beef, with one addition that has no beef equivalent.

1. The Hump: The Primal Beef Does Not Have

The bison hump sits over the shoulder and forward rib, supported by dramatically elongated dorsal spinal processes extending upward from the vertebrae. Cattle have nothing comparable. The muscle covering that bone structure is a genuine primal in its own right and is usually taken as a hump roast.

Removing it is a separate operation before the forequarter is broken down conventionally, because the bone structure underneath does not correspond to anything in a beef fabrication sequence.

[CHEF: how you take the hump, what it weighs on a typical animal, how you portion it, and how you cook it. This is the single most distinctive thing about bison fabrication and the part a competitor cannot copy from a beef guide. Your method here is the reason this page should rank.]

2. Forequarter vs. Hindquarter Overview

The carcass divides between the 12th and 13th ribs.

  • Forequarter: Hump, chuck, rib, brisket, shank and plate. Carries structural weight, producing collagen-dense cuts that reward long cooking.
  • Hindquarter: Short loin, sirloin, flank and round. Contains the least-worked muscles along the spine and the lean rear leg.

3. Fat Distribution: External Cap, Almost No Marbling

  • External fat cap: Where most bison fat lives. Protect it. Trimming to a beef finish removes what little insulation the meat has during cooking.
  • Intramuscular marbling: Minimal. Do not expect the visual cues used to judge a beef ribeye. Their absence is normal and is not a fault in the animal.
  • Collagen: Present as in beef, surrounding muscle bundles, converting to gelatin during slow moist cooking above 160°F (71°C).
  • Silverskin: A shiny membrane that never dissolves and must be trimmed manually. More visible and more of a job on bison than on beef.

Aging Bison: Why the Rules Change

1. Dry Aging a Lean Carcass

Dry aging hangs bare primals in a controlled cooler at 34-36°F (1-2°C) with 80-85% relative humidity and steady airflow, allowing enzymes to tenderize while evaporation concentrates flavor. On beef this costs 15-20% in weight loss to the trimmed pellicle.

The arithmetic is less favorable on bison. Dry aging depends on an exterior fat cap to protect the muscle underneath from drying out. A leaner carcass has less protection, so more of what is lost is meat rather than moisture and trim.

[CHEF: whether you dry age bison at all, and for how long if so. This is a judgement call I should not make for you.]

2. Wet Aging in Vacuum Bags

Wet aging is the sensible default for bison and the right method for beginners. Subprimals are vacuum-sealed in oxygen-impermeable bags and refrigerated at 34-36°F (1-2°C). It achieves enzymatic tenderization with no moisture loss and no crust to trim, which suits an animal that cannot spare the surface.

Step-by-Step Guide: Fabricating the Bison Forequarter

Step 1: Removing the Hump

This step comes first and has no beef equivalent. The hump muscle sits over elongated vertebral processes and is released before the forequarter is broken down conventionally.

[CHEF: the sequence, in your numbered-step format. Where the first cut goes, how the blade follows the spinal processes, whether the saw is needed and where.]

Step 2: Removing and Deboning the Brisket and Shank

  1. Place the forequarter bone-side up on the cutting table.
  2. Cut straight across the lower breast, sawing through the arm bone to detach the foreshank and brisket section.
  3. Separate the foreshank from the brisket along the natural fat seam.
  4. Debone the brisket flat and point. Trim the surface fat cap to an even 1/4-inch. Do not go below this on bison, because there is no interior fat to make up for it during a long cook.

A bison brisket headed for a smoker is a harder proposition than a beef one, because a lean brisket dries through the stall rather than rendering through it. The Meathead Method covers fire management, bark formation and the stall in the detail that decides whether a lean brisket survives.

Step 3: Separating the Chuck Primal from the Rib Primal

  1. Count to the space between the 5th and 6th ribs.
  2. Make a straight incision through muscle between those ribs, starting at the spine and cutting down toward the plate.
  3. Saw through the rib bones and spine to separate the chuck primal from the standing rib primal.

Step 4: Fabricating Standing Rib Roasts and Boneless Ribeyes

  1. Trim exterior fat along the rib rack to expose the rib eye muscle, leaving more cap than a beef finish would call for.
  2. For a standing rib roast, slice between ribs to create 2-rib or 3-rib roasts with bones intact.
  3. For boneless ribeyes, run a stiff boning knife flush against the rib and chine bones to release the whole ribeye roll, then slice crosswise into steaks with a smooth pulling motion.

Cut bison ribeyes thicker than beef ribeyes. A thicker steak gives a wider margin between a seared exterior and an overcooked center, and that margin is the thing lean meat does not otherwise have. [CHEF: your preferred thickness. Beef guide says 1.5 inches.]

Step 5: Breaking Down the Chuck

  1. Locate the shoulder blade. Run the boning knife beneath it to free it cleanly.
  2. Remove the top blade muscle from the shoulder blade. Slice horizontally through its center to remove the internal connective sheath, isolating two flat iron steaks.
  3. Divide the remaining chuck along natural seams into chuck eye roasts, shoulder clod roasts and stew meat.

Step-by-Step Guide: Fabricating the Bison Hindquarter

Step 1: Removing the Flank Muscle

Slice along the natural fat seam connecting the thin flank muscle to the sirloin and round. Trim the surface membrane. Flank is coarse-grained and, on an animal this lean, is a cut that must be sliced thinly across the grain or not served at all.

Step 2: Separating the Loin Primal from the Round

Locate the pelvic pin bone and sacral vertebrae. Saw through the pelvic joint between the 4th and 5th lumbar vertebrae to separate the whole loin primal from the round.

Step 3: Fabricating Short Loin Steaks

  1. Divide the loin into short loin and sirloin by cutting just in front of the hip bone.
  2. Keep the bone intact and cut crosswise with the saw to produce T-bone steaks from the front and porterhouse steaks from the rear, where the tenderloin section is wider.
  3. Alternatively strip the bone and tenderloin off to yield a boneless strip loin, sliced crosswise into strip steaks.

Step 4: Extracting and Trimming the Whole Tenderloin

  1. Reach into the interior spine cavity of the uncut short loin.
  2. Using fingers and short boning knife strokes, peel the psoas major away from the lumbar vertebrae.
  3. Lay the whole tenderloin on the board. Slip the knife tip under the silverskin and slide smooth strokes down its length to remove it completely.
  4. Cut the thick center section into uniform steaks.

The bison tenderloin is the leanest cut on the leanest common red meat. It is the single easiest thing on the carcass to ruin, and it is worth cooking first while attention is high rather than last.

Step 5: Seam Breakdown of the Round

  1. Hang the round leg by the shank bone.
  2. Locate the seam in front of the femur. Insert the knife tip and slice downward to release the sirloin tip.
  3. Trace the interior seam along the pelvic bone to release the top round.
  4. Peel the outer muscles apart along membrane lines to separate bottom round and the cylindrical eye of round.
  5. Debone the femur and collect lean trim for grinding.

The round is where a bison harvest diverges most from beef in practice. These are already the leanest muscles on a lean animal, and roasting them whole to a beef schedule produces something closer to jerky. Much of the round is better ground, cured, or braised than roasted.

Step-by-Step Guide: Grinding Bison and the Fat Question

Step 1: Choosing and Adding Fat to a Lean Grind

This is the section with no beef equivalent, and it is the one most beginners get wrong.

Beef trim grinds to a usable burger on its own because the animal supplies its own fat. Bison does not. Ground straight, bison trim produces a patty that crumbles on the grill and eats dry regardless of how carefully it is cooked. Fat has to be added.

The three usual approaches, each with a real trade-off:

  • Add beef fat. Beef suet or fat trim blended into bison lean. Straightforward, widely available, and the result tastes partly of beef.
  • Add pork fat. Common in sausage work. Softer, milder, and it changes the character more than beef fat does.
  • Keep it lean and change what it is for. Accept the leanness, grind without additions, and use it in chili, sauces and braises rather than patties, where added liquid and long cooking do the work fat would have done.

[CHEF: which of these you use, and at what ratio. This is the single most-asked bison question and your answer is the reason someone would read this page instead of a beef one.]

Step 2: Executing the Double-Grind

Cut meat and any added fat into 1-inch cubes. Place cubed meat and the grinder throat components in the freezer for 30 to 45 minutes until firm and icy at the edges, around 32-34°F. Pass through a coarse 3/8-inch plate first, mix thoroughly by hand to distribute the added fat, then pass a second time through a fine 3/16-inch plate.

The mixing step between passes matters more on bison than beef. Added fat sits where it is put and will not redistribute itself the way marbling does.

Step 3: Rendering Bison Tallow, and Whether It Is Worth It

Rendering follows the same method as beef. Chop or coarse-grind hard fat, place in a heavy stockpot over low heat with a splash of water, and hold gently for 2 to 3 hours until the fat melts clear and cracklings float. Strain through cheesecloth into glass jars.

The honest caveat is quantity. A bison carcass yields far less renderable fat than a beef carcass of comparable size, so the return on the same three hours is smaller. Whether it is worth doing depends on how much fat came off the animal, which varies with age, season and finish.

Three hours on low heat is where a thin pot scorches the fat and turns the result dark instead of clean. A 4.5-Qt Ceramic Nonstick Stock Pot spreads low heat evenly across the base and releases the cracklings without scraping.

Packaging and Long-Term Freezer Storage

1. Vacuum Sealing Techniques

Pat surfaces thoroughly dry before bagging, because moisture along the bag edge prevents a liquid-tight seal. Double-seal openings for long-term storage. Lean meat suffers freezer burn faster than fatty meat, so seal quality matters more on bison than beef.

2. Labeling and USDA Freezing Schedules

Mark every package with a waterproof marker: cut name, weight and date. Store flat in a chest freezer at 0°F (-18°C) or colder.

USDA guidance for bison specifically:

  • Freeze ground bison within 2 days of purchase, larger cuts within 3 to 5 days.
  • Frozen ground bison holds best quality for about 4 months.
  • Larger frozen cuts hold best quality for 6 to 9 months.

Those windows are shorter than the 12 months commonly quoted for vacuum-sealed beef, which is consistent with a leaner product being more exposed to oxidation and dehydration.

Beginner Culinary Guide: How to Cook Every Cut Without Ruining It

This is where bison actually costs people their harvest. The butchery is not hard. The cooking is where a freezer full of good meat gets turned into something disappointing, and the cause is always the same: cooking it on a beef schedule.

1. Fast, Hot Searing for Lean Steaks

Season steaks generously with kosher salt and black pepper and bring them closer to room temperature than a beef steak, so less time in the pan is needed to reach the center. Heat a heavy skillet over high heat until lightly smoking. Sear hard and fast, basting with butter, crushed garlic and rosemary in the final minute. Butter is doing real work here, supplying fat the animal did not.

Pull earlier than instinct says. Carryover cooking behaves the same on bison as on beef, but the consequence of overshooting is greater because there is no melting marbling to disguise it. USDA gives 145°F (63°C) with a 3-minute rest as the safe minimum for whole-muscle cuts.

Thermal mass is the whole trick. A cold thick steak pulls the temperature out of a light pan and steams instead of searing. An 11 inch Enameled Cast Iron Grill Pan carries enough heat to hold its sear through both sides.

2. Dutch Oven Braising for Collagen-Dense Cuts

For hump roast, chuck, shank and much of the round, sear the exterior first, then submerge halfway in stock, wine and aromatics, cover tightly and braise at 275°F (135°C) until collagen converts to gelatin and the meat shreds with a fork.

Braising is the friendlier half of bison cookery, because moist heat supplies what the animal lacks. A larger proportion of a bison carcass belongs in a braise than a beef carcass does, and treating that as a feature rather than a compromise is the shift that makes the freezer worthwhile.

Sear and braise in the same vessel or the fond is lost, and the fond is most of the flavor. An Enameled Cast Iron Round Dutch Oven takes the stovetop sear and the oven without changing pans, and the 10 Quart Oval Dutch Oven handles a whole hump roast or chuck roast. Both are in the pots, pans and cookware collection.

10 Common Beginner Bison Butchering Mistakes to Avoid

  1. Trimming to a Beef Finish: Removing the external fat cap to the standard beef thickness strips away most of the fat the animal has. Leave more than instinct suggests.
  2. Grinding Without Adding Fat: Straight bison trim will not hold together as a burger. Decide on a fat strategy before the grinder comes out, not after tasting the first patty.
  3. Cooking to a Beef Schedule: The same target temperature reached over the same time produces a drier result. Pull earlier and cut steaks thicker.
  4. Roasting the Round Whole: The leanest muscles on a lean animal do not reward dry roasting. Braise, cure or grind them.
  5. Sawing Across Muscle Seams: Follow the white membrane lines with a flexible boning knife. On bison they are easier to see than on beef, so there is less excuse.
  6. Fabricating Warm Meat: Above 40°F the surfaces turn slippery and the fat smears. Keep quarters chilled.
  7. Leaving Silverskin On: It contracts under heat, curls the steak and eats tough. There is more of it to remove here than on beef.
  8. Dulling Knives on Bone: Use joint cartilage seams or the saw. Bison bone is heavy and unforgiving of a fine boning blade.
  9. Assuming Inspection: Bison inspection is voluntary rather than mandatory. Know the source and what inspection, if any, it carried.
  10. Freezing to Beef Timelines: USDA quality windows for bison are shorter. Label with dates and work through the freezer accordingly.

Mistake eight compounds across a long day. A quarter takes hours, and an edge dulled early makes every remaining cut worse. A Professional Electric Knife Sharpener resets a blade between primals so the last steak off the loin is as clean as the first.

Frequently Asked Questions

Is bison inspected by the USDA like beef?
Not in the same way. USDA Food Safety and Inspection Service states that bison may be inspected under voluntary federal inspection or FDA-equivalent inspection, rather than the mandatory inspection that applies to beef, pork and lamb. An inspection legend on bison reflects a producer's choice rather than a legal requirement.

How much leaner is bison than beef, really?
Substantially. USDA figures give raw separable lean bison as 109 calories and 1.8 grams of fat per 100 grams, against 291 calories and 24 grams of fat for USDA Choice beef. That difference drives nearly every handling and cooking decision on this page.

Why does my ground bison fall apart on the grill?
Because there is not enough fat in it to bind the patty. Bison does not supply its own burger fat the way beef does. Either blend in beef or pork fat before grinding, or use the grind in chili, sauces and braises where it does not need to hold a shape.

What temperature should I cook bison to?
USDA gives 145°F (63°C) with a 3-minute rest for steaks and roasts, and 160°F (71°C) for ground bison. Cooks who take beef to medium rare often do the same with bison, which is a personal risk decision rather than a USDA recommendation. Whatever the target, use a thermometer, because the margin for overshooting is smaller than it is on beef.

Final Thoughts on Your First Bison Fabrication Project

Bison is the animal that teaches a butcher to stop working on autopilot. The seams are familiar and easier to read than beef, so the fabrication itself often goes more smoothly than expected. What catches people out comes afterward: the grind that will not hold together, the roast that came out dry, the freezer package that lost quality months earlier than a beef one would have. Every one of those traces back to the same 1.8 grams of fat per 100 grams. Work with the leanness rather than against it, leave more fat on than instinct suggests, pull the meat off the heat earlier than feels right, and send more of the animal to the braising pot than you would with beef.
