Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Tripe
Ingredients
Directions
Prepare the tripe
Soak the tripe in cold water overnight.
Wash the tripe in warm water with soda, but do not soak it.
Place the tripe in cold water and boil. If the water smells unpleasant, change it and boil again.
Simmer gently for about 6 hours.
Add the onions 1 hour before the tripe is done.
Make the sauce
Skin the onions. Scald the onions. Chop the onions.
Mix flour with milk. Add ½ pint of the tripe cooking liquid. Boil for 5 minutes.
Finish and serve
Cut the tripe into neat pieces. Combine the tripe with the sauce. Season with pepper and salt. Serve.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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 stew and becomes tender through long, gentle simmering.
- Flour
- Thickens the milk and cooking liquid into a smooth sauce.
- Milk
- Adds creaminess and body to the sauce.
- Onions
- Add sweetness and aroma as they soften in the stew.
The step that matters
Simmer gently for about 6 hours. Tripe is tough connective tissue. Slow, gentle simmering at low heat breaks it down and makes it tender, while a hard boil can toughen and shrink it.
Swap the onion
How well each one fits the dish's main ingredients (flour, milk, pepper):
- Capsicumfits better
- Arrowrootfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
