1 medium sweet potato
1 to 2 cups icing sugar
1/2 teaspoon almond flavoring
1/4 teaspoon rosewater extract
Bake potato, scrape out pulp and put through a coarse sieve. Add icing sugar a cup at first and then flavorings. Mix, then knead until it forms a smooth dough like paste. Add more icing sugar if needed. Sprinkle board with icing sugar and roll out paste to 1/4-inch thickness to fit size and shape of cake to be covered. Brush cake surface with slightly beaten egg white, then add almond paste. Allow to stand overnight before adding ornamental frosting. This makes enough for top and sides of a cake 5x5x3-inches.
