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

What each ingredient does

Dried peas
Break down during long boiling to thicken the soup and give it body.
Butter
Stirred in cold at the end to add richness and a silkier mouthfeel.
Onions
Release sweetness and savory flavor as they soften in the simmering broth.
Celery
Adds aromatic, savory depth to the soup base as it simmers.

The step that matters

Adding more water during the second boil. Peas keep absorbing liquid and thickening as they cook, so the soup can turn too thick and scorch. Adding water as needed keeps the texture smooth and the soup from sticking to the pot.

Swap the peas

How well each one fits the dish's main ingredients (onion, celery, carrot, turnip, pepper, butter, bread):
