Mix together the grated rind of a lemon, a teaspoonful of cinnamon, half a spoonful of ground cloves, one grated nutmeg, about three ounces of citron very finely minced, and a teaspoonful of baking-powder. Now blend thoroughly with one pound of sifted flour and work in four whipped eggs and one pound of castor sugar. Make this into small balls and place them in a buttered baking-dish not too close together, as they should swell considerably in the cooking. Bake them carefully in a slow oven.
