Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato Sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as its starch swells in the hot fat and liquid.
- Tomatoes
- Provide the main body, colour and acidic tang of the sauce.
- White stock
- Supplies the liquid and savoury depth that carries the sauce.
- Butter
- Adds richness and a rounded, mellow flavour to the base.
- Onions
- Build an aromatic, lightly sweet base as they soften in the fat.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes.
The step that matters
Cook until the flour begins to brown. Cooking the flour in fat drives off its raw, pasty taste and adds colour and nutty flavour. Taking it too far scorches the starch, making the sauce bitter and dark.
Swap the tomato
How well each one fits the dish's main ingredients (pork, carrot, onion, flour, butter, sugar, pepper):
- Potatofits better
- Capsicumfits better
- Turnipfits better
- Tomatothe original
Fit is the average pairing score against pork, carrot, onion, flour, butter, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
