Work quickly as you remove tuiles from the baking sheet so they'll mold easily into a cup. Although you can make the sherbet up to a day ahead, the tuiles don't keep well--make them a few hours ahead, garnish, and then store in an airtight container.
1 ounce semisweet or white chocolate, finely chopped
2 tablespoons sparkling sugar
How to Make It
To prepare sherbet, combine first 4 ingredients in a medium saucepan. Bring to a boil; cook 1 minute or until sugar dissolves. Remove from heat. Place pan in a large ice-filled bowl for 15 minutes or until mixture chills, stirring occasionally.
Place sugar mixture, cranberries, liqueur, and juice in a food processor or blender; process until smooth. Press cranberry mixture through a fine sieve over a bowl; discard solids. Add cream to cranberry mixture in bowl; stir well.
Pour mixture into the freezer can of an ice-cream freezer; freeze according to manufacturer's instructions. Spoon sherbet into a freezer-safe container; cover and freeze at least 3 hours or until firm.
Preheat oven to 350°.
To prepare tuiles, combine 6 tablespoons sugar and next 4 ingredients (through dash of salt) in a bowl, stirring with a whisk. Add 3 tablespoons milk, vanilla, and egg white; stir until smooth. Add oil and butter, stirring until well combined.
Coat a baking sheet with baking spray. Using your finger, draw 3 (6-inch) circles about 5 inches apart on baking sheet. Spoon 2 tablespoons batter onto each circle, spreading to edges of circles using the back of a spoon. Bake at 350° for 15 minutes or until browned. Loosen edges of tuiles with a spatula; remove from baking sheet. Working quickly, gently shape each tuile over a 4-inch-tall spice jar or small juice glass to form a shallow scalloped cup; cool completely. (Tuiles are delicate and should be handled carefully when shaped.) Repeat procedure with remaining batter.
Place the chocolate in a microwave-safe bowl, and microwave at HIGH 1 minute or until chocolate almost melts, stirring until smooth. Place sparkling sugar in a shallow bowl. Gently coat edges of tuiles with melted chocolate using a small brush, and sprinkle chocolate with sparkling sugar. Let stand for 5 minutes or until firm. Spoon 1/2 cup sherbet into each tuile. Serve immediately.
