I remember growing up eating Polvorone Biscuits in Belize, I thought they were primarily from Belize or Mexico, but I discovered that the origin of polvorones is Spain. It is a type of heavy, soft and very crumbly shortbread. It is made with flour, milk, sugar and nuts. It is popular all over Spain and ex-Spanish colonies during the Christmas period. The ones in Belize didn't have nuts, so I made them that way.
