Why did my white chocolate seize into a stiff, grainy clump?

Water got into it, even a single drop or a puff of steam from the double boiler. Melted chocolate seizes instantly on contact with water and cannot be smoothed back out for bark. Always use a completely dry bowl and utensils, keep simmering water well below the bowl, and wipe the bottom of the bowl before you start stirring in flavorings.

Why are my two chocolate layers separating when I break the bark?

The dark layer was too cold when the white chocolate went on. If the dark layer chills in the fridge, the warm white chocolate contracts at a different rate and the layers delaminate. Let the dark layer set at room temperature until firm but not cold, about 10 to 15 minutes, then pour the white chocolate over it.

Can I use chocolate chips instead of chopped bar chocolate?

You can, but the bark will not be as good. Chips contain stabilizers that help them hold their shape, which also makes them resist tempering, so the snap and shine suffer. Chopped bar chocolate or wafers melt smoothly and temper properly, which is the whole point of this recipe.

Why did the red stripes on my candy canes bleed into the white chocolate?

Humidity is the culprit, almost always from refrigerating the finished bark. Cold storage makes the candy absorb moisture, turn sticky, and bleed color. Set and store the bark at cool room temperature in an airtight container, and only refrigerate if your kitchen is genuinely warm.

How much peppermint extract is too much for peppermint bark?

More than 3/4 teaspoon per 12 ounces of white chocolate starts tasting medicinal. This recipe uses 1/2 teaspoon, which gives bright mint flavor without harshness. If you substitute peppermint oil, which is three to four times stronger than extract, use only 1/8 teaspoon. Never use generic mint extract, which tastes like toothpaste next to true peppermint.

Cook Mode Prevent your screen from going dark

Instructions

Line a quarter sheet pan or 9 by 13 inch baking pan with parchment paper, leaving overhang on two sides for easy lifting.Place the candy canes in a sturdy zip-top bag, press out the air, and crush with a rolling pin into small shards and bits (not powder).Chop both chocolates into roughly half inch pieces and keep in separate bowls. Set aside about 3 ounces of the dark chocolate as seed chocolate.Melt the remaining 9 ounces of dark chocolate in a heatproof bowl over barely simmering water, stirring gently, keeping all water and steam away. Melt until smooth.Remove from heat, wipe the bowl bottom dry, and stir in the seed chocolate a little at a time until melted and the chocolate cools to about 88 to 90 degrees F and looks glossy.Pour the tempered dark chocolate onto the prepared pan and spread into an even layer about 1/4 inch thick. Let sit at cool room temperature 10 to 15 minutes, until set but not cold.Melt the white chocolate gently in a clean, completely dry bowl (double boiler or microwave in 20 second bursts), stopping when a few pieces remain and stirring smooth. Stir in the peppermint extract.Pour the white chocolate over the dark layer, spread gently to the edges, and drag a skewer lightly through once or twice for a marbled look.Immediately sprinkle the crushed candy canes evenly over the surface and press very lightly with wax paper. Add the pinch of flaky salt if using.Leave undisturbed at cool room temperature about 1 hour until completely firm. Lift out by the parchment and break into irregular pieces.
