Almond paste is also know as Marzipan and can usually be found in the baking section of your local store.

Marzipan is used in making cakes and pastries and is often used as a base for making icing. It can used in confectionery to make petits fours or formed into shapes for presentation.

The word marzipan is derived from the Italian marzapane which originally meant a sweet box, but has long since been associated with its contents.
