Almond Letters Messapine Recipe

Referred to by family members as just Messapine.
It is a traditional treat at Christmas.
Mother mixes up the pastry and dough and invites one of the daughters to help her roll it out the following day.
The notable differences in our recipes are the addition of baking pwdr and the way it is rolled out.

Well worth the effort and a fun evening for mother and daughter.
