Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Break down into a sweet, savoury base that gives the soup body once sieved.
- Turnip
- Adds earthy flavour and body to the vegetable purée.
- Milk
- Forms the creamy liquid base of the soup and adds richness.
- French potato flour
- Thickens the milk as it heats, giving the soup a smooth, velvety body.
The step that matters
Letting the milk boil before thickening. Milk can scorch on the bottom of the pan and boil over quickly, so it needs watching. Starch thickens best in a hot liquid, so the flour mixture should be stirred in evenly to avoid lumps.
Swap the turnip
How well each one fits the dish's main ingredients (onion, celery, milk, potato, bread):
- Carrotfits better
- Tomatofits better
- Leekfits better
- Turnipthe original
Fit is the average pairing score against onion, celery, milk, potato, bread. Candidates are from the same food group and used in at least 100 recipes.
