LAYERED PEPPERMINT CRUNCH BARK
Slightly tweaked from Epicurious. This bark is surprisingly restrained; it isn't exceptionally sweet, and there's enough mint to redeem the waxy blandness of the white chocolate. (I've been known to pour the peppermint extract generously, approaching a full teaspoon in total.)
For the dark chocolate, I aim for the middle of the road and use mostly semisweet and some bittersweet if I have both on hand. The combination seems to be the most universally appealing, which is an asset if you're making these for gifts or a party. Use whichever suits your fancy or your audience. Since semisweet chocolate is quite a bit softer than bittersweet, in that case I cut the cream down to 4 1/2-5 tablespoons.
I have discovered that the red swirly peppermints called for are named "Starlight Mints" - could that be more charming? Pounding the pretties to an uneven dust affords the texture we like best. The tiny shards snap and the larger chunks crunch, but no piece is so large as to give any real resistance.
30 red-and-white-striped hard peppermint candies, crushed fairly fine (about 6 ounces)
17 ounces good-quality white chocolate (such as Lindt or Baker's), finely chopped
A good pinch kosher salt
7 ounces bittersweet (not unsweetened) or semisweet chocolate, chopped
6 tablespoons whipping cream
3/4 teaspoon peppermint extract
Run the peppermints through a coarse sieve. Reserve the dust to one side, and keep the larger pieces in the sieve itself.
Turn a large, sturdy baking sheet face side down. Cover securely with foil. Mark a 12x9-inch rectangle on the foil. Place the chopped white chocolate and kosher salt in a metal bowl over a saucepan of barely simmering water, never allowing the bottom of the bowl to touch the water. Stir until chocolate is melted and smooth, and registers 110°F on a candy thermometer. Remove the bowl from the water. Pour 2/3 cup of the melted white chocolate within border of the marked rectangle on foil. Using an offset spatula, spread chocolate to fill the rectangle. Mix some of the larger peppermint pieces into the dust to make up 1/3 cup. Sprinkle this over the white chocolate and chill until firm, about 15 minutes.
Stir the dark chocolate, cream and peppermint extract in a heavy-bottomed saucepan over medium-low heat until smooth. Cool to barely lukewarm, around 5 minutes. Pour the bittersweet chocolate mixture over the white chocolate rectangle. Using a clean offset spatula, spread the bittersweet chocolate to form an even layer. Chill until very cold and firm, around 25 minutes.
Rewarm the remaining white chocolate in bowl set over barely simmering water, again to 110°F. Working quickly, pour the white chocolate over the firm bittersweet chocolate layer, spreading with a clean offset spatula to cover. Immediately sprinkle with remaining crushed peppermints. Refrigerate until just firm, about 20 minutes.
Lift bark off the foil onto a large work surface, with a metal spatula as aid if needed. With a thin bladed knife, trim edges. Cut bark crosswise into 2-inch-wide lengths. Cut each strip crosswise into 3 sections and each section across into squares.
Can be kept, in an airtight container in the refrigerator, for up to 2 weeks. Seperate layers with wax paper to keep candies from sticking.
Serve straight from the fridge or allow to sit at room temperature for 10 minutes or so if a softer candy is preferred. For the record, if you stash some in the freezer and then bash it to smaller shards, it makes a fine topping to a scoop of vanilla ice cream.
Makes 36 pieces.
