Why it works: Chicken and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Tripe, Stewed
Ingredients
Directions
Prepare the tripe
Remove any fat from the cooked tripe and pour hot water over it, then let it cool and pour off the water.
Cut the tripe into pieces and add to a pot with the stock.
Bring to a boil.
Stew
Stir in the chopped onion, salt, and pepper.
Add a thickening of flour and butter or flour only.
If desired, add a small amount of boiled rice or other grain.
If using uncooked tripe, double the stock amount and cook the tripe in it until tender after boiling it in salted water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked tripe
- Forms the main body of the dish and becomes tender with slow stewing.
- Chicken or rabbit stock
- Provides the cooking liquid and moisture that gives the stew its body.
- Flour
- Thickens the stock into a smooth, lightly bodied sauce.
- Butter
- Adds richness and helps the flour thicken the liquid smoothly.
The step that matters
Adding the flour and butter thickening. Flour added directly to hot liquid clumps, so it should be blended with butter into a smooth paste first. Whisking it in gradually lets starch granules swell evenly and thicken the stew without lumps.
Swap the onion
How well each one fits the dish's main ingredients (chicken, pepper, flour, butter):
- Capsicumfits better
- Potatofits better
- Leekfits about as well
- Onionthe original
Fit is the average pairing score against chicken, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
