Parboil the tripe in boiling water for 3-4 min. and immediately grate (clean) its inside with a knife.
Then clean it on the outside as well, remove the membrane. Wash it, put it in a pot and pour cold water over it.
Boil it, while constantly topping off with water. Boiling it takes about 3 hours. While the tripe is boiling, you have to keep it covered with water.
Upon serving, put some of the tripe in a bowl and pour the hot broth over it, along with mashed garlic and vinegar.
Serve with chili peppers if desired.
