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, becoming tender as it stews.
- Onion
- Adds aromatic sweetness and flavor as it softens in the stew.
- Tomatoes
- Contribute acidity and moisture, giving the sauce its body and bright flavor.
- Thickening
- Binds the liquid into a sauce by swelling with heat and gelatinizing starch.
The step that matters
Stir in the thickening before adding the tomatoes. Starch needs heat and liquid to swell and thicken, so stirring it in while the stew is hot and well mixed prevents lumps and a thin, uneven sauce. Adding acidic tomatoes at this point keeps the thickening working in a well-blended liquid.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, flour):
- Capsicumfits better
- Okrafits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
