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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Tomatoes
- Form the base of the sauce, providing bulk, flavour and body once pureed.
- Shallots
- Add a mild, sweet aromatic flavour as they soften in the butter.
- Vinegar
- Adds acidity that brightens the flavour and balances the sweetness of the tomatoes.
The step that matters
Stew until soft, then press through a wire sieve. Cooking the tomatoes and shallots gently until fully soft breaks down their cell walls, so the puree passes smoothly through the sieve. Under-cooked pieces stay fibrous and leave the sauce grainy.
Swap the tomato
How well each one fits the dish's main ingredients (butter, shallot, pepper, vinegar):
- Mustardfits better
