Preparation / Directions:
Preheat oven to 350 degrees. Spread the almonds on a baking sheet and toast, stirring occasionally, until lightly browned and fragrant, about 8 minutes. Remove from oven and cool.
Line 2 large, heavy baking sheets with aluminum foil. Lightly butter the foil.
In a heavy saucepan over medium heat, combine the cream, granulated sugar, brown sugar, and butter. Cook, stirring constantly, just until the sugars dissolve and the butter melts. Add the almonds, flour and orange and lemon zests. Bring to a boil, stirring constantly. Remove from the heat.
Drop 1 rounded teaspoon batter (batter will be runny) onto a prepared baking sheet. Repeat with more batter, spacing the cookies at lest 2 inches apart. Repeat with the second baking sheet.
Bake until deep brown, about 8 minutes, switching the pans and rotating a half turn halfway through baking. Remove from the oven. Slide the foil off each sheet with the cookies in place. Line the same sheets with new foil, butter the foil, and repeat with remaining batter.
While all 4 sheets of cookies are cooling completely on their pieces of foil, line the baking sheets with new foil. Carefully peel the cookies off the foil and arrange them, smooth side up, on the newly covered baking sheets. Combine the semisweet and unsweetened chocolates in the top pan of a double boiler or in a heatproof bowl. Place over simmering water in the bottom pan and heat, stirring frequently, until melted and smooth. Remove from the heat.
Using an icing spatula or a knife, spread the chocolate over the flat side of each cookie and return to the baking sheets, chocolate side up. Refrigerate, uncovered, until the chocolate sets. Store in an airtight container in the refrigerator for up to 2 weeks.
