Why it works: Butter and milk 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 ↓
Tripe, Baked
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the tripe in cold water and cut it into neat squares.
Slice the onions and fry them lightly in butter.
Place the fried onions in an earthen baking dish with a lid.
Bake
Lay the tripe on top of the onions and sprinkle with flour, pepper, and salt.
Cover the tripe with milk and put on the lid.
Bake in a moderate oven at 350°F (175°C) for about 1.5 hours.
Serve
Skim the fat from the top and serve the tripe on a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the dish and becomes tender during long, slow baking in milk.
- Onions
- Add sweetness and savour as they soften and cook down beneath the tripe.
- Butter
- Adds richness and helps the onions brown lightly before baking.
- Flour
- Sprinkled over the tripe, it thickens the milk into a light sauce as it bakes.
- Milk
- Covers the tripe and gently braises it, producing a mild, creamy sauce.
The step that matters
Baking with the lid on. Covering the dish traps steam so the tripe braises gently in the milk; uncovered, the milk can reduce and scorch while the tripe stays tough.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, milk):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
