Pulp the remaining ingredients through a coarse sieve.
Return the pulp to the soup.

Simmer until the celery is tender.

Simmer and finish
Bring water to a full boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Thicken the soup when mashed and pureed, giving it body and a smooth texture.
- Stock
- Forms the liquid base that carries the flavour of the soup.
- Celery
- Adds aroma and a subtle savoury flavour as it softens in the soup.
- Peas
- Add sweetness and body when cooked and pulped into the soup.
- Leeks
- Contribute a mild onion-like aroma and sweetness as they cook.
The step that matters
Passing the potatoes through a sieve after boiling. Potatoes must be boiled until very dry and then mashed smoothly; wet or lumpy potatoes turn gluey or grainy, so the texture depends on how dry and fine they are before adding the stock.
Swap the peas
How well each one fits the dish's main ingredients (celery, onion, potato, leek, sugar, pepper):
- Beansfits better
- Lentilsfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against celery, onion, potato, leek, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
