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

What each ingredient does

Butter
Carries the heat for frying and adds rich flavor to the vegetables.
Onion
Softens and turns mildly sweet when fried, building the soup's aromatic base.
Carrots
Release natural sugars as they cook, adding gentle sweetness and color.
Dry peas
Their starch softens and thickens the broth, giving it body.
Dry mushrooms
Add savory, umami depth to the broth.

The step that matters

Frying the vegetables in butter until the moisture evaporates. Driving off water lets the vegetables brown slightly and concentrate their sugars instead of steaming. Rushing this step leaves the soup watery and flat in flavor.

Swap the onion

How well each one fits the dish's main ingredients (carrot, turnip, celery, lettuce, leek, butter, fish):
