yep tripe (aka cow stomach) we use that in dishes as well...but I have never tried it either...
1 pound beef tripe, cut into small squares
3 fresh cloves garlic, minced
3 teaspoons salt
1/2 cup red chile powder
2 teaspoons oregano leaves
1 tablespoons coarse black pepper
1 teaspoons cumin powder
1/2 small onion chopped
1 small can hominy, yellow or white
beef tripe into a pot of boiling water, just enough to cover the tripe.
Add garlic and onions and salt. Cover and cook for about 1 hour. When
tripe is tender add the remaining ingredients including the hominy and
cook about 15 or 20 minutes longer. Add more salt if needed. This is a
spicy dish and it goes well with cilantro and a twist of lime. Corn
tortillas are a good compliment.
