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
Prepare the celery
Cook the chopped celery in boiling water until very soft.
Press the cooked celery through a sieve to obtain 2 cups of stock and pulp.
Make the soup
In a pot, melt the butter, then stir in the flour, salt, and pepper.
Gradually add the celery stock and milk, stirring constantly until thickened.
Add onion juice to taste and serve hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup into a smooth, creamy base when cooked with the butter and liquid.
- Butter
- Adds fat that carries flavor and helps form the smooth roux with the flour.
- Milk
- Adds creaminess and body to the soup as it thickens.
- Celery
- Provides the main celery flavor and, as pulp, adds body to the stock.
The step that matters
Stirring the liquid in gradually. Adding the stock and milk slowly while stirring constantly keeps the flour dispersed, so the soup thickens smoothly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (celery, flour, pepper, butter, milk):
- Carrotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against celery, flour, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
