Roll a pound of puff paste to about an eighth of an inch in thickness and cut out about thirty rounds with a fluted cutter, about two and a half inches in diameter. Then cut out the center of these with a cutter about an inch across. Roll out the paste taken from the centers and cut out more rings in the same way. Brush the rings over with egg, place one on top of another, two by two, press together so that they will stick, place on a baking sheet, brush over with egg and bake in a brisk oven. When almost done sprinkle with sugar and allow to remain in the oven till they are glazed and fully done. Remove and place on a warmed platter and fill with any sort of cream desired, or jam or tart marmalade.
