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.
Mutton
Adds rich meaty flavor and fat to the broth as it simmers.
Carrots
Add sweetness and color, and soften into the broth.
Turnips
Contribute mild sweetness and soften into the broth.
Celery
Adds a fresh, aromatic note when added near the end.

The step that matters

Boiling the peas for 2 hours. Dried peas need a long, steady boil to soften fully and release their starch, which thickens the soup. Stopping early leaves them firm and the soup thin.

Swap the peas

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