Roll out half the almond paste between sheets of plastic wrap to form a 10-inch round. Remove the top sheet of plastic wrap, fit the almond paste layer over one cake, trimming the edge if necessary, and remove the other sheet of plastic wrap. Repeat with the remaining almond paste and cake.
10 To make the icing: In a bowl with an electric mixer, beat 4 cups of the confectioners' sugar, the egg whites, and the lemon juice for 4 to 6 minutes, or until the mixture holds soft peaks. Beat in the remaining 3 cups of confectioners' sugar and beat until the icing holds stiff peaks.
11 Transfer 2 cups of the icing to a pastry bag fitted with a decorative tip. Spread the remaining icing on the tops and sides of the cakes with a long metal spatula. Pipe the icing decoratively onto the cakes and arrange the silver dragees on top.
Note
Storage: Wrap the finished cakes tightly in plastic wrap. Store at room temperature for up to several months. Do not refrigerate, as the cold can dry out the cake.
Substitutions: If you cannot find Manischewitz wine, use any sweet red dessert wine or port. Dark rum can be substituted with dark rum-flavored extract mixed with water, though the flavor will be less complex.
Tips: For a deeper color, you can add 3 ounces of burnt sugar or 6 ounces of gravy coloring to the batter before baking, as mentioned in the original source notes.
Variations: Some traditional recipes call for soaking the fruit in tawny port instead of wine and rum. You can also brush the cooled cakes with additional port or rum before icing for extra moisture.
