Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the body of the dish, becoming tender during parboiling and stewing.
- Onion
- Adds sweetness and aroma as it softens in the stew.
- Thickening
- Thickens the liquid into a sauce as starch swells with heat.
- Tomatoes
- Adds acidity and body to the sauce.
The step that matters
Drain off the first water after parboiling. Parboiling releases impurities and off-flavours from the tripe into the water. Discarding that first water before stewing keeps the final sauce clean-tasting.
Swap the onion
How well each one fits the dish's main ingredients (flour, tomato, pepper):
- Capsicumfits better
- Okrafits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against flour, tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
