Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Celery Soup
Ingredients
Directions
Make the broth
Boil the celery in beef stock with onion, salt, pepper, and parsley for about 1 hour.
Strain the mixture.
Finish the soup
In a separate pot, heat the milk and thicken it with flour and creamed butter.
Add the strained mixture to the thickened milk along with 1 cup of boiled celery.
If desired, stir in sweet cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavor and body of the soup as it simmers in the stock.
- Butter
- Enriches the thickened milk and adds a rich, smooth mouthfeel.
- Flour
- Thickens the milk into a smooth, body-rich base when cooked with the butter.
- Milk
- Forms the creamy base of the soup, mellowed by the thickening.
- Beef stock
- Carries the celery's flavor and adds savory depth during the long simmer.
The step that matters
Thickening the milk with flour and butter. Flour must be cooked smoothly into the butter and milk; if it is added lumpy or left under-heated, the soup stays grainy or tastes raw-floury.
Swap the parsley
How well each one fits the dish's main ingredients (celery, butter, cream, flour, onion, milk, beef):
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
- Garlicfits about as well
Fit is the average pairing score against celery, butter, cream, flour, onion, milk, beef. Candidates are from the same food group and used in at least 100 recipes.
