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 saucepan, melt the butter, then add the flour and stir until smooth.
Gradually add the celery stock and milk, and stir constantly until thickened.
Add the celery pulp and onion juice.
Season with salt and pepper.

Butter and flour 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
- Celery
- Provides the main flavour and, once pulped, body to the soup.
- Butter
- Adds richness and carries flavour as the base of the roux.
- Flour
- Thickens the liquid into a smooth, creamy sauce when cooked with butter and milk.
- Milk
- Adds creaminess and softens the soup's flavour.
The step that matters
Stir the milk and stock in gradually. Adding liquid slowly to the butter and flour roux lets the starch disperse evenly, preventing lumps and giving a smooth, thickened base.
Swap the onion
How well each one fits the dish's main ingredients (celery, pepper, butter, milk, flour):
- Carrotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against celery, pepper, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
