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 ↓
Tomato Sauce
Ingredients
Directions
Prepare
Break the tomatoes into small pieces.
Place the pieces in a stewpan.
Add butter or gravy, salt, and pepper if desired.
Cook
Simmer gently for 45 minutes.
Strain and thicken
Rub the mixture through a sieve, ensuring no seeds remain.
Return the puree to the stewpan.
Stir over heat until thickened, like good apple sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the bulk of the pulp and liquid that simmer down into the sauce.
- Butter
- Adds fat for a smoother, richer mouthfeel and rounder flavour.
The step that matters
Stir over heat until thickened. As water evaporates, the puree thickens and can scorch on the base of the pan. Frequent stirring over gentle heat keeps it smooth and evenly thickened.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Tomatothe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
