Why it works: Celery and turnip are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,418 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Celery Soup
Ingredients
Directions
Prepare the vegetables
Strip the green part from the celery, using only the white.
Cut it into shreds, reserving the inside of 3 roots.
Slice the turnip and onion, then place them in a pan with the celery.
Make the soup
Add 2 quarts of water, bread crumbs, and salt.
Boil until the vegetables are soft.
Rub the mixture through a sieve and return it to the pan.
Add the reserved celery (boiled until soft), butter, and flour mixed well.
Stir in white pepper, mace, and more salt if needed.
Boil for 15 minutes.
Stir in the cream, but do not allow it to boil afterwards.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and body of the soup once rubbed through a sieve.
- Turnip
- Adds bulk and a mild sweetness that thickens the soup as it cooks down.
- Bread crumbs
- Absorb liquid and help thicken the puree, giving the soup more body.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- Flour
- Thickens the soup slightly when stirred in with the butter.
- Cream
- Adds richness and a silky texture when stirred in at the end.
The step that matters
Stir in the cream without boiling. Boiling cream after adding it can cause it to separate or curdle and turn grainy, so it should only be warmed through once stirred in.
Swap the white pepper
How well each one fits the dish's main ingredients (celery, turnip, onion, bread, butter, flour, cream):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against celery, turnip, onion, bread, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
