Mantecados

A polvorón is a type of heavy, soft, and very crumbly Spanish shortbread made of flour, sugar, milk, and nuts (especially almonds). They are mostly produced in Andalusia, where there are about 70 factories that are part of a syndicate that produces polvorones and mantecados. Under the name mantecados, these sweets are a traditional preparation of other areas of the Iberian Peninsula and other Spanish-speaking countries as well. Polvorones are popular holiday delicacies in all of Spain, Hispanic America, the Philippines, and other Spanish-influenced countries around the world. Traditionally, they were prepared from September to January, but they are now available all year round. Mantecado is a name for a variety of Spanish shortbreads that includes the polvorón. The names are often synonymous, but not all mantecados are polvorones. The name mantecado comes from manteca (lard), usually the fat of Iberian pig (cerdo ibérico), with which they are made, while the name polvorón is based on the fact that these cakes crumble easily into a kind of dust in the hand or the mouth.
