To Boil Tripe
Ingredients
Directions
Prepare
Cut the tripe into moderately sized pieces.
Place the tripe in a pot and cover with water.
Cook and serve
Simmer the tripe slowly for 6–12 hours, depending on its age.
Once tender, serve the tripe in a hash dish with some of the cooking water and boiled onions.
For a flavorful option, stew the boiled tripe in a saucepan with milk for about 10 minutes.

What each ingredient does
- Tripe
- Is the main ingredient; slow simmering makes its tough connective tissue tender.
- Milk
- Adds richness and a mild, creamy flavor when the boiled tripe is stewed in it.
The step that matters
Simmer slowly until tender. Tripe is tough connective tissue. A gentle, slow simmer breaks down collagen into gelatin, which makes it tender. A hard boil can toughen the meat and make it rubbery, so the time needed depends on the tripe's age.
