Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
To Boil Tripe
Ingredients
Directions
Prepare and simmer
Cut the tripe into moderately sized pieces.
Place the tripe in a pot and cover with water.
Simmer the tripe slowly for 6-12 hours, depending on its age, until tender.
Serve
Serve the tripe in a hash dish with some of the boiling water and boiled onions.
Milk variation
For a tasty variation, remove the tripe from the water and stew it in a saucepan with milk.
Thicken the milk with arrowroot or a mixture of flour and butter, and season with pepper and coarse sea salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Long, slow simmering softens its connective tissue, making the main meat tender.
- Onions
- Boiling mellows their sharpness and adds a mild, sweet flavour to the dish.
- Milk
- Forms the base of the creamy variation sauce that the tripe is stewed in.
- Arrowroot or flour
- Starch swells in the hot milk and thickens it into a smooth sauce.
- Butter
- Adds fat and richness, and combines with flour to form a thickening base.
The step that matters
Simmer slowly, not at a rolling boil. Vigorous boiling toughens the muscle proteins and makes tripe rubbery. Gentle heat over many hours slowly breaks down connective tissue, so the tripe becomes tender throughout.
Swap the arrowroot
How well each one fits the dish's main ingredients (onion, milk, butter, pepper):
- Potatofits better
