Baking: Spread about 1 teaspoon cold tuille batter thinly over stencils (professional or homemade) on greased back of cookie sheet. Place tuiles in 350 degree F oven. Tuiles will spread and cook rapidly. Therefore, test a few, one at a time, for appropriate thinness of batter and length of cooking time. If tuiles have spread too much, reduce amount of batter and make sure batter is spread evenly and thinly. Tuiles should be removed from oven when slightly golden. Let set for a few seconds on sheet before removing to rack for cooling.
Assemble Napoleon by layering tuiles and fruit compote. Top with ice cream, frozen yogurt, or whipped cream.
