Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Form the body of the puree as they soften and break down during cooking.
- Ham bone
- Adds savoury depth and flavour to the stock as it simmers with the peas.
- Onion
- Builds aromatic sweetness and flavour base when braised at the start.
- Carrot
- Adds subtle sweetness and body to the flavour base.
- Celery
- Contributes aromatic savouriness to the flavour base.
- Stock
- Provides liquid that cooks the peas and sets the final thickness of the puree.
The step that matters
Rub through a fine sieve. Pushing the cooked peas through a fine sieve breaks them into a smooth purée. Skipping or rushing this leaves a grainy texture, since unbroken pea skins and fibres stay in the soup.
Swap the peas
How well each one fits the dish's main ingredients (ham, onion, carrot, celery, pepper):
- Beansfits better
- Black-eyed peafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against ham, onion, carrot, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
