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 stock
In a separate pot, cover the cut celery with cold water and cook for about 3 hours or longer.
Strain the celery stock through cheesecloth.
Make the soup
Rub together the flour and butter in a bowl.
Heat the milk in a saucepan and gradually stir in the flour and butter mixture.
Add the celery stock to the milk mixture.
Combine the strained stock with the milk mixture and season with salt, black pepper, cayenne pepper, and onion if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a creamy, smooth soup.
- Butter
- Enriches the soup and helps the flour blend smoothly into the milk.
- Milk
- Forms the creamy base of the soup.
- Celery
- Provides the main flavor, cooked into the stock.
The step that matters
Gradually stirring the flour and butter into the hot milk. Adding the flour-butter mixture slowly and stirring keeps it dispersed, so it thickens evenly instead of forming lumps.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (flour, butter, milk, celery, pepper):
- Carrotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against flour, butter, milk, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
