guatitas ("[little] guts" or "[little] bellies", from ; "gut/belly"), or guatitas criollas, is a popular dish in chile and in ecuador, where it is considered a national dish. it is essentially a stew whose main ingredient is pieces of tripe (cow stomach), known locally as "guatitas". the tripe is often cleaned several times in a lemon-juice brine, after which it is cooked for a long time until the meat is tender. then it is allowed to cool and finely chopped. there are various vegetarian versions of the dish in which wheat gluten is substituted for tripe. other variations use strong-tasting fish such as tuna. the traditional ecuadorian recipe is served hot and accompanied by potatoes and a peanut sauce.
