Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Brown Celery Soup
Ingredients
Directions
Prepare the celery
Remove the heart of the celery, shred it finely, and set aside.
Cut up the remaining celery and boil it in the quart of stock until tender.
Make the soup
Boil the shredded celery in the stock until tender.
Rub the cooked celery through a sieve into the stock.
Mix the potato flour with a small amount of cold stock or water, then add it to the soup.
Return the soup to the saucepan and stir over heat until boiling.
Serve
Place the shredded celery in a tureen and pour the soup over it.
Serve with croutons.

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, with the sieved portion thickening the stock.
- Brown stock
- Forms the liquid base that carries the celery flavour through the soup.
- Potato flour
- Thickens the soup as it comes to the boil, giving it a smoother, heavier texture.
The step that matters
Stirring the thickened soup up to the boil. Potato flour must be mixed smoothly into cold liquid first, then heated while stirring. Adding it dry or letting it sit unstirred causes lumps, and the starch only thickens fully once the liquid boils.
Swap the potato
How well each one fits the dish's main ingredients (celery, flour, pepper):
- Carrotfits better
- Turnipfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against celery, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
