Morcillas, or blood sausages are known in many different countries, including Latin America. Some love 'em, some hate 'em, some are just like "oh hell nah, I'm not eating blood. Kthxbai"
I have never tried them, but I don't think I could stomach them. However, if there was an incentive like a $10,000 -- I'd eat like it was my last meal. But for some people -- it's a delicacy, it can be a favorite. But thinking about it, I totally could have already tried it, and not have not known what it was, because more often than not, I try new foods.
Morcillas in Latin America are cooked differently. In Puerto Rico, they are fried and eaten on special occasions. In some South American countries, it's thrown on a grill.
