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 Soup
Ingredients
Directions
Make the celery base
Bring 3 pints of boiling water to a boil in a pot.
Add 3 cups of finely chopped celery and cook until tender.
Rub the cooked celery through a sieve to create a puree.
Make the soup
In a separate saucepan, heat 1 pint of milk with 1 tablespoon of butter and 1 tablespoon of flour to thicken.
Combine the celery puree with the thickened milk.
Season with celery salt, salt, and pepper to taste.
Simmer for 10 minutes.
Just before serving, stir in 1 cup of scalded cream.

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.

Butter and flour 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, once pureed, the body of the soup.
- Milk
- Forms the creamy liquid base that the puree is combined with.
- Butter
- Adds richness and fat that carries flavour in the sauce.
- Flour
- Thickens the milk mixture so the soup becomes smooth and creamy.
- Scalded cream
- Adds richness and a silkier mouthfeel when stirred in at the end.
The step that matters
Thickening the milk with butter and flour. Flour must be cooked with the butter and warm milk while stirring so it dissolves without lumps; uncooked flour tastes raw and can leave the soup grainy or pasty.
Swap the celery
How well each one fits the dish's main ingredients (milk, butter, flour, pepper, cream):
- Nutmegfits better
- Cinnamonfits better
- Cardamomfits about as well
- Celerythe original
Fit is the average pairing score against milk, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
