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 flavor of the puree once softened and strained.
Butter
Carries the onion in frying and forms the base of the roux.
Flour
Thickens the puree when cooked with butter into a roux and blended in.
Onion
Adds savory flavor as it softens in butter without browning.

The step that matters

Cook the roux without browning. Flour and onion that brown take on a darker, bitter taste and a different color, and the flour thickens less well. Cooking gently keeps the puree light and smooth.

Swap the tomato
