Almond Sponge Cake

Original Recipe

The addition of almonds makes this cake very superior to the usual sponge cake. Sift one pint of fine flour; blanch in scalding water two ounces of sweet and two ounces of bitter almonds, renewing the hot water when expedient; when the skins are all off wash the almonds in cold water (mixing the sweet and bitter) and wipe them dry; pound them to a fine, smooth paste (one at a time), adding, as you proceed, water or white of egg to prevent their boiling. Set them in a cool place; beat ten eggs, the whites and yolks separately, till very smooth and thick, and then beat into them gradually two cups powdered sugar in turn with the pounded almonds; lastly, add the flour, stirring it round slowly and lightly on the surface of the mixture, as in common sponge cake; have ready buttered a deep square pan; put the mixture carefully into it, set into the oven and bake till thoroughly done and risen very high; when cool, cover it with plain white icing flavored with rose-water, or with almond icing. With sweet almonds always use a small portion of bitter; without them, sweet almonds have little or no taste, though they add to the richness of the cake. Use two heaping teaspoonfuls of baking powder in the flour.
