Orange Sandwich.—Grate the yellow outer part of one orange, after washing it well, and press out the juice. Put ½lb. of flour, 3oz. of sugar, and 2oz. of butter into a basin, and sift into it half a teaspoonful of soda; mix the butter carefully into the flour till it is quite rubbed down. Put the yolks of three eggs into a basin and beat them well; add to them the grated orange, rind and juice, and mix thoroughly; then add one teaspoonful of cream of tartar, and stir again; pour all into the basin with the flour, etc., and mix well. Beat the whites of the three eggs until stiff, and stir them in, pour all into two well-buttered sandwich cake tins, or two soup plates, and bake till ready. When cool, split and spread with the following mixture: One orange, 3oz. of icing sugar, one white of egg. Grate the rind of the orange, press out the juice and mix into the sugar, beat the white of egg stiffly, and stir in. Spread it over the cakes, put the two sides together, cut neatly, and serve.
