Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the soup and thicken it as they break down.
- Onions
- Brown in butter to add sweetness and savory depth.
- Carrots
- Add natural sweetness and color to the soup.
- Turnips
- Contribute mild sweetness and body once cooked and sieved.
- Butter
- Adds fat that carries flavor and helps the vegetables brown.
- Celery
- Adds a fresh, aromatic note to the finished soup.
The step that matters
Gently fry onions, carrots, and turnips until browned. Browning triggers the Maillard reaction, which builds deeper, savory flavor. Heat that is too high or frying too long can scorch the sugars and make the soup bitter.

Fit is the average pairing score against onion, carrot, turnip, butter, pepper, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
