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
Ingredients
Directions
Prepare the celery

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy base of the soup and gives it body and mild sweetness.
- Flour
- Thickens the soup as it cooks, giving it a smooth, velvety body.
- Butter
- Adds fat for richer flavour and a smoother mouthfeel.
- Celery
- Provides the main flavour and, once mashed, the bulk of the soup's texture.
The step that matters
Cooking the flour mixture. Flour must be cooked long enough to lose its raw starchy taste and to fully thicken. Stirring it into the milk without cooking it properly can leave the soup pasty or floury.
Swap the mace
How well each one fits the dish's main ingredients (milk, flour, butter, celery, onion, pepper, cream):
- Parsleyfits better
- Nutmegfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against milk, flour, butter, celery, onion, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
