here's something i found on the internet about marzipan...hope this helps.
Marzipan is an almond and sugar paste used to ice cakes and other pastries or sculpted into a variety of shapes to be eaten as candy or used as cake decorations. Marzipan is simply a mixture of almond paste, powdered sugar, and a moistening agent such as water, corn syrup, glucose, fondant, or egg whites. After the ingredients are mixed, marzipan reaches a consistency of dough or soft rubber and can be rolled, shaped, cut, or molded.
Because marzipan is both delicious to eat on its own and simple to make, it is often used both as the icing for cakes and as decoration. When used to ice a cake, marzipan is rolled into a thin sheet and draped over the cake, usually with a fruit glaze applied between the cake and marzipan so that the icing sticks more securely. Once the marzipan is draped over the cake, the sides are carefully smoothed down so that the icing is uniform and free of bubbles or wrinkles
