Curtido is a type of lightly fermented cabbage relish. It is typical in Salvadoran cuisine and that of other Central American countries, and is usually made with cabbage, onions, carrots, oregano, and sometimes lime juice; it resembles sauerkraut, kimchi, or tart coleslaw. It is commonly served alongside pupusas, the national delicacy.
Fellow Central American country Belize has a similar recipe called "curtido" by its Spanish speakers; however, it is a spicy, fermented relish made with onions, habaneros, and vinegar. It is used to top salbutes, garnaches, and other common dishes in Belizean cuisine.
