Put a large cupful of water in a saucepan; add 2 ounces of butter, ¼ teaspoonful of salt, 1 tablespoonful of pulverized sugar. While boiling, stir in sifted flour until stiff and smooth. Remove from the stove and stir in the yolks of 4 eggs, one at a time, and the beaten whites; then fry by the teaspoonful in boiling lard until browned. Serve with a caramel sauce.
