Cognac-Laced Truffles

1/4 cup cognac
1/2 heavy cream
11 ounces semi-sweet chocolate, chopped
3 ounces white baking chocolate, chopped
1 ounce unsweetened chocolate, chopped
3/4 cup powdered sugar

Coating:
2 tablespoons unsweetened cocoa powder
2 tablespoons powdered (confectioners') sugar

Line 2 baking sheets with waxed paper. Heat cognac in a small saucepan just to simmering. Remove from heat. Add cream. Bring to simmering.

Place all the chocolate and 3/4 cup confectioners' sugar in a food processor and whirl 1 to 2 minutes or until finely chopped. With machine running, add cream mixture in a steady stream. Process until smooth. Scrape into a medium-size bowl. Refrigerate just until thick enough to hold shape, about 1 hour.

Drop by rounded teaspoonfuls onto prepared baking sheets. With your hands, quickly shape into balls. (Refrigerate to firm while working if necessary.) Place in freezer 30 minutes.

Prepare coating: Sift cocoa powder and confectioners' sugar into a small bowl. Add truffles, 3 at a time; toss to coat. Refrigerate in airtight containers up to 1 month. Serve at room temperature.

Yields 42 truffles.
