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 ↓
Cream of Celery Soup
Ingredients
Directions
Make the celery base
Boil the chopped celery and onion in 2 quarts of water for 1.5 hours.
Ensure 1 pint of water remains after cooking.
Finish the soup
In a double boiler, heat 1 pint of milk.
Mash and sieve the cooked celery mixture, then add it to the milk.
Stir in the remaining water, salt, pepper, and butter.
Thicken the soup with cornstarch as desired.

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 cooked and sieved.
- Milk
- Adds creaminess and a smooth, rich texture to the soup.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Cornstarch
- Thickens the soup as the starch gelatinises when heated.
The step that matters
Thickening with cornstarch. Cornstarch must be heated in liquid to gelatinise and thicken; added to cold liquid or left unstirred, it clumps or stays thin. Adding it gradually while stirring keeps the soup smooth.
Swap the onion
How well each one fits the dish's main ingredients (celery, milk, butter, egg, pepper):

- Carrotfits better
- Onionthe original
Fit is the average pairing score against celery, milk, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
