Why it works: Leek and celery match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,093 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sturgeon-soup, with Curry
Ingredients
Directions
Prepare the sturgeon
Remove the skin from the sturgeon and wash it.
Season the sturgeon and braise it with vegetables, wine, and broth.
Make the soup
In a separate pan, fry the minced onions, leek, and celery root in butter.
Moisten the fried vegetables with fish broth and the cooking stock from the sturgeon.
Bring the mixture to a boil, then reduce heat and add a bunch of parsley and aromatics.
Thicken the soup with a mixture of curry powder and rice flour diluted in cold broth.
Boil the soup for 30 minutes, then skim off the fat and strain it through a sieve.
Add the sturgeon meat cut into small squares and the boiled rice to the soup.
Bring the soup to a simmer and thicken it with a mixture of egg yolks.
Serve the soup in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Thickens the broth into a smooth, body-rich soup as its starch gelatinizes.
- Egg yolks
- Enrich and thicken the soup with a silky texture when gently heated.
- Butter
- Carries the flavour of the fried onions, leek and celery root and adds richness.
- Curry powder
- Adds the warm, spiced aroma that defines the soup.
- Fresh sturgeon
- Supplies the firm, mild fish meat that forms the body of the soup.
The step that matters
Thickening with egg yolks. If the soup boils after the yolks go in, they scramble and turn grainy. Bring it only to a simmer, or temper the yolks first, so it stays smooth and silky.
Swap the celery
How well each one fits the dish's main ingredients (sturgeon, onion, leek, fish, rice, egg, butter):
- Capersfits better
- Parsleyfits better
- Thymefits about as well
- Celerythe original
Fit is the average pairing score against sturgeon, onion, leek, fish, rice, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
