Make broad noodles with three eggs. Boil until tender, drain, pouring cold water through colander. Stew prunes, sprinkle with sugar and cinnamon. In a well-greased baking-dish place one-quarter of the noodles, bits of butter or other fat, add one-half of the prunes, then another layer of the noodles, butter or fat, the remaining prunes, the rest of the noodles. Pour over the prune juice and spread crumbs over top and bake in a moderate oven until crumbs are brown.
