2 1/2 cups fresh raspberries or thawed frozen unsweetened raspberries
1/2 cup superfine sugar
1/4 cup framboise or other raspberry-flavored liqueur (optional)
To make the raspberry sauce, place the raspberries, sugar and framboise, if using, in a blender or in a food processor fitted with the metal blade. Puree until smooth. If you prefer a seedless sauce, pass the puree through a sieve.
