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 ↓
Tripe Stewed
Ingredients
Directions
Prepare the tripe
Boil the tripe for a sufficient time to make it tender, then pour off the water.
Replace the water with milk and bring it to a boil.
Parboil and chop the onions, then add them to the tripe and milk.
Thicken and serve
In a small bowl, mix the flour, pepper, and salt with a little cold milk until smooth.
Add the flour mixture to the saucepan and boil for 15 minutes.
Serve hot.

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 boiling.
- Flour
- Thickens the milky liquid into a smooth, lightly bodied stew.
- Onions
- Add sweetness and aroma as they soften into the milk.
- Milk (in the method)
- Forms the creamy cooking liquid that gives the stew its body and mild sweetness.
The step that matters
Mixing the flour with cold milk before adding it. Flour added directly to hot liquid clumps, because its starch surface hydrates unevenly. Blending it smooth in cold milk first lets it disperse evenly, so the stew thickens without lumps.
Swap the onion
How well each one fits the dish's main ingredients (flour, pepper):
- Arrowrootfits better
- Okrafits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
