Beat the egg whites until stiff.
Stir remaining ingredients, except for the butter, together. Mix well. Fold the beaten egg whites into the mixture. Shape dough into small dumplings and place in a baking dish. Melt butter and pour over dumplings.
Bake 6 to 8 minutes in a preheated 350° oven.
These dumplings are especially good with chicken fricassee, but because they are light and fluffy, they may be used in many ways.
