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

What each ingredient does

Split peas
Provide the main body and thickness of the puree as they soften and break down.
Butter
Adds richness and a silky mouthfeel to the finished puree.
Onions
Build savory flavor when fried gently in butter before simmering.
Carrots
Add natural sweetness and color while softening into the puree.

The step that matters

Rub the mixture through a fine sieve. Pushing the softened peas and vegetables through a fine sieve breaks down remaining fibers and skins, giving the smooth, even texture the puree depends on. Skipping or rushing this leaves a grainy result.

Swap the white pepper

How well each one fits the dish's main ingredients (peas, carrot, onion, celery, butter, sugar, mint):
