Can you freeze almond paste?
A basic Google search hit on numerous sites all which agree that almond paste can be frozen with no deterioration of the product.  The key is to wrap it up in several layers of plastic bags or plastic, then aluminum foil to keep out other flavors from the freezer as my experience has been that ground nuts will absorb odors if improperly wrapped.  

Once in the freezer, hopefully in manageable-sized packages for easy thaw and use, the almond paste should keep for several months at least.  

I've stored ground almonds in the freezer for a year with no harm to the flavor.

Best of luck!
