Roll puff paste one-eighth inch thick. Shape with a fluted round cutter, first dipped in flour; with a smaller cutter remove centres from half the pieces, leaving rings one-half inch wide. Brush with cold water the larger pieces near the edge; fit on rings, pressing lightly. Chill thoroughly, and bake fifteen minutes in hot oven. By brushing tops of rings with beaten yolk of egg diluted with one teaspoonful water, they will have a glazed appearance. Cool, and fill with jam or jelly.
