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 ↓

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
- Celery
- Provides the main flavour and body of the soup once boiled and sieved.
- White stock
- Cooks the celery and forms the liquid base of the soup.
- Butter
- Adds richness and fat, carrying flavour through the soup.
- Flour
- Thickens the soup by absorbing liquid and swelling when heated.
- Milk or cream
- Adds creaminess and a softer, smoother texture to the soup.
The step that matters
Rubbing the mixture through a sieve. Pressing the cooked celery through a sieve breaks down fibres and yields a smooth texture. Skipping or rushing this leaves the soup stringy and grainy.
Swap the celery
How well each one fits the dish's main ingredients (milk, flour, butter, pepper):
- Cinnamonfits better
- Nutmegfits better
- Cardamomfits better
- Celerythe original
Fit is the average pairing score against milk, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
