If you must be on one of those cabbage diets, at least fill it with Curtido. The Central American relish resembles a kimchi or sauerkraut.

The Spanish food is popular in El Salvador where it is eaten with their sandwich, the Pupusa. The sandwich is like a tortilla which is filled with savoury items and Curtido for tang.

The fermented relish is spicy and made with habanero, onions and vinegar.
