Roll puff paste in a long rectangular piece, one-eighth inch thick. Cut in strips three-fourths inch wide. Roll paste over wooden forms bought for the purpose, having edges overlap. Bake in hot oven until well puffed and slightly browned. Brush over with white of egg slightly beaten, diluted with one teaspoon water, then sprinkle with sugar. Return to oven and finish cooking, and remove from forms. When cold, fill with Cream Filling or whipped cream sweetened and flavored.
