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
Prepare the celery
Wash the celery, cut it into small pieces, and boil until soft in just enough boiling water to cover it.
Press the celery through a strainer, saving the cooking water.
Make the soup
Scald the milk.
Mix the flour with a little cold milk to smooth out lumps.
Add the flour mixture to the hot milk, stirring constantly, and boil for about five minutes.
Add the salt, pepper, and butter.
Then add the strained celery and the reserved cooking water.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 milk into a smooth, creamy body as it cooks.
- Butter
- Adds richness and a silky mouthfeel to the soup.
- Milk
- Forms the creamy base of the soup.
- Celery
- Provides the main flavour and the bulk of the soup when pressed through a strainer.
The step that matters
Mix the flour with cold milk before adding it to the hot milk. Flour clumps when it meets hot liquid directly. Blending it first with a little cold milk separates the particles so they disperse evenly, and constant stirring while it boils keeps the thickener smooth.
Swap the celery
How well each one fits the dish's main ingredients (flour, butter, pepper, milk):
- Cinnamonfits better
- Nutmegfits better
- Cardamomfits better
- Celerythe original
Fit is the average pairing score against flour, butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
