Since this recipe does not contain egg, it is safe to let frozen almond paste thaw on your counter-top for use in your favorite recipes. If the almond paste happens to be too stiff to handle after storage, it can be sufficiently softened by placing it in top part of double boiler and heat over hot, not boiling, water until it's soft enough to handle.
If you don't know the fabulous things you can do with almond paste, put it in the search engine and see what comes up! That's just the tip of the iceberg!!!
