About 2/3 cup per serving. Dissolve gelatin in boiling water, stirring until crystals disappear. In a blender or the workbowl of a food processor fitted with a metal blade, blend dissolved gelatin, tofu, apple juice concentrate, vanilla, brown sugar, cinnamon and 1 cup of blueberries until smooth. Pour pudding into a bowl; fold in remaining cup of blueberries. Cover with plastic wrap and refrigerate for 4 hours, or until set. Serve cold. The sweetener in this recipe is apple juice concentrate. It's a good way to cut down on processed sugar. Serves 4.
