Peppermint Bark

Preparation

1. Step 1

   Line a rimmed baking sheet with parchment paper and set aside. Set 12 ounces/340 grams semisweet chocolate in a microwave-safe bowl and microwave it in 5- to 25-second bursts, stirring occasionally, until it is melted and the temperature registers between 114 degrees and 118 degrees on an instant-read thermometer. Chocolate burns easily in the microwave, so go slowly. Try fewer seconds as the temperature starts getting close so that you don’t overshoot the mark. (If you’re a few degrees over, just keeping stirring the chocolate until it cools to the proper temperature.)

2. Step 2

   Remove the bowl from the microwave and gradually stir in the remaining 4 ounces/115 grams semisweet chocolate until the temperature has come down to 88 to 89 degrees. (After a bit of practice you can actually see and feel the chocolate fall into temper. It takes on a slightly looser quality and becomes shinier. Be patient, this can take up to 10 to 12 minutes with some chocolate.) Now quickly pour the chocolate out onto the prepared pan and spread it into an even layer. Let the chocolate stand at room temperature until the layer has set, about 1 hour. (You can also refrigerate until set, about 30 minutes.)

3. Step 3

   Now set 6 ounces/170 grams white chocolate in a microwave-safe bowl and microwave it in 5- to 25-second bursts, stirring occasionally, until it is melted and the temperature registers between 105 degrees and 110 degrees on an instant-read thermometer.

4. Step 4

   Remove the bowl from the microwave and gradually stir in the remaining 2 ounces/55 grams white chocolate until the temperature has come down to about 85 degrees. Quickly stir in the peppermint extract. Drizzle the white chocolate mixture evenly over the semisweet chocolate. Immediately sprinkle with the candy cane.

5. Step 5

   Let stand at room temperature until completely set, about 4 hours. To serve, break into pieces. Refrigerate leftover pieces as necessary.
