Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Form the main body and bright, acidic flavour of the purée.
Brown stock
Adds savoury depth and liquid to thin and carry the tomato flavour.
Butter
Carries the onion's flavour and adds richness to the purée.
Onion
Adds sweet, savoury aromatic flavour once softened in butter.
Flour (in the method)
Thickens the onion mixture so the purée becomes smooth and body-rich.

The step that matters

Sauté the onion until soft but not browned. Browning changes the onion's flavour toward bitter and caramelised notes that would colour the pale purée. Gentle cooking softens the cells so the mixture strains smoothly and blends evenly.

Swap the onion
