Melted chocolate that sets without tempering turns pale, streaky, and soft, because the cocoa butter crystals re-form randomly as it cools. Tempering forces the cocoa butter into one stable crystal structure, which is what gives good chocolate its glossy shine and the audible snap when you break it, rather than a dull, fudgy give.
The easiest home method is seeding: melt most of the chocolate, then stir in a handful of unmelted chocolate at the end. The solid pieces carry stable crystals into the melted batch and guide the whole thing to set correctly as it cools, no thermometer or marble slab required.
Chocolate Bark with Mix-Ins
Serves 4. Prep 15 minutes, chill 30 minutes.
Ingredients
- 12 ounces good quality chocolate, chopped, divided
- 1/2 cup mixed toasted nuts, roughly chopped
- 1/4 cup dried cranberries or cherries
- 2 tablespoons flaky sea salt or crushed pretzels, optional
Method
- Set aside about a quarter of the chopped chocolate, this is your seed chocolate.
- Melt the remaining three-quarters over a double boiler or in short microwave bursts, stirring often, until fully smooth.
- Remove from heat and stir in the reserved chopped chocolate a little at a time, stirring until each addition fully melts before adding more, until the chocolate feels just barely cool to the touch and looks glossy.
- Pour the tempered chocolate onto a parchment-lined sheet and spread to an even, thin layer with an offset spatula.
- Scatter the nuts, dried fruit, and salt or pretzels evenly over the top while the chocolate is still wet, pressing lightly so they adhere.
- Let set at cool room temperature, or chill 20 to 30 minutes if your kitchen runs warm.
- Break into irregular pieces once fully set.

Tips and Variations
- Two-tone bark: spread a layer of white chocolate over set dark chocolate and swirl with a toothpick for a marbled look.
- Test the temper before pouring: dab a small amount on parchment, if it sets glossy and hard within a few minutes at room temperature, the batch is tempered.
- Keep water away entirely: even a single drop of water in melted chocolate can cause it to seize and turn grainy, dry every tool first.
- Store it cool: bark holds up to two weeks in an airtight container in a cool spot, away from direct sunlight or heat.
Frequently Asked Questions
Why did my chocolate turn out dull and streaky?
It was not properly tempered, the cocoa butter crystals set randomly instead of in the stable structure seeding provides.
Why did my chocolate seize into a grainy clump?
Water got into the chocolate at some point, even a small amount. Keep every bowl and utensil completely dry.
Can I use chocolate chips?
You can, but chips often contain stabilizers that make tempering less reliable, a bar of eating chocolate tempers more predictably.
Does this need to be refrigerated?
Properly tempered bark holds fine at cool room temperature, refrigeration can actually cause condensation that dulls the surface once it comes back out.
Tools for the Job
Clean, uniform pieces come from a mold that portions the bark before it's broken by hand.
