It’s a Mexican soup made with beef tripe, the stomach lining of the cow, and hominy. Currently, the dish can be found at restaurants all over San Antonio, but most prefer a homemade bowl. Clean and cut beef tripe into small pieces. In a large pot put beef tripe and pour water into the pot until filled just over the tripe. After 3 hours of stewing taste to see if beef tripe is soft enough to eat and not too chewy.
