Why it works: Pepper and celery 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 soup
Combine milk, flour, cornstarch, a dash of red pepper, a slice of onion, and a blade of mace in a double boiler and bring to a boil.

Stir in the butter over low heat until fully blended.
Serve
Serve the soup in a hot tureen, then add whipped cream if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that gives the soup its body and creamy richness.
- Flour
- Thickens the milk as it heats, giving the soup body.
- Cornstarch
- Adds further thickening so the soup becomes smooth and velvety.
- Celery
- Provides the main flavor and, once mashed, the soup's bulk and texture.
- Butter
- Adds fat that gives a smooth, rich mouthfeel and a silkier finish.
The step that matters
Bringing the milk, flour and cornstarch to a boil. Flour and cornstarch must be fully heated in the liquid to swell and thicken. Stirring keeps the starches dispersed, which prevents lumps and a pasty texture.
Swap the mace
How well each one fits the dish's main ingredients (milk, flour, pepper, onion, celery, butter, cream):
- Parsleyfits better
- Nutmegfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against milk, flour, pepper, onion, celery, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
