Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Stew
Ingredients
Directions
Prepare the meat
Dredge the meat heavily with flour and fry in a frying pan until very brown.
If using onion, slice it and add to the meat while frying.
Cook the stew
Transfer the meat to a kettle, add salt and a small amount of water, and cook slowly for 1 hour.
Add the tomatoes and peppers, and continue cooking slowly for 1.5 hours.
Add more water if necessary, using broth for gravy and adding thickening if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiling meat
- Provides the main body of the stew and, after slow cooking, becomes tender.
- Flour
- Coats the meat so it browns deeply and later helps thicken the gravy.
- Canned tomatoes
- Add acidity and liquid that form the base of the sauce.
- Spanish peppers
- Add flavour and body to the sauce as they cook slowly with the tomatoes.
The step that matters
Browning the floured meat. Frying the flour-coated meat until very brown builds deep roasted flavour through the Maillard reaction and helps the flour form a crust. Pale meat gives a flat, less savoury stew.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, tomato, pepper, flour):
- Capsicumfits better
- Okrafits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against meat, tomato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
