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):
