ALMOND ICING

Whites of four eggs; one pound sweet almonds; one pound powdered sugar; a little rose-water. Blanch the almonds by pouring boiling water over them and stripping off the skins. When dry, pound them to a paste, a few at a time, in a Wedgewood mortar, moistening it with rose-water as you go on. When beaten fine and smooth, beat gradually into icing. Put on very thick, and, when nearly dry, cover with plain icing.
