Morcilla, sometimes called "bloodmeal" in english, is a deli product made from the blood of livestock, usually pigs. During processing, the blood is gathered and combined with preservatives and stabilizers, to create a solid mass. The solid mass is seasoned, fried, and when cooked looks like bits of sausage.
Though not common on costarrican tables, morcilla is sold at most butcher shops. It is a product fit for human consumption, and has no relation with bloodmeal fertilizer , used in organic gardening.
