Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Give the soup its sweetness, body and colour when cooked and sieved.
- Butter
- Adds richness and fat, giving the soup a smooth, rounded mouthfeel.
- Onion
- Adds savoury depth and aroma as it softens into the base.
- Turnip
- Contributes body and a mild, slightly peppery flavour to the soup.
- Celery
- Adds aromatic, savoury flavour that supports the vegetable base.
The step that matters
Rub the mixture through a fine sieve, gradually adding the reserved cooking water. Pushing the very soft vegetables through a sieve breaks down their cell walls into a smooth purée. Adding the cooking water a little at a time lets you control thickness so the soup does not become too thick or grainy.
Swap the onion
How well each one fits the dish's main ingredients (carrot, butter, sugar, turnip, celery):

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