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 stock
Cook the celery in boiling water until very soft.
Press the cooked celery through a strainer to obtain 4 cups of stock.
Finish the soup
In a separate pot, heat the milk with onion juice and add to the celery stock.
In a small bowl, mix the flour with a little water to create a smooth paste, then stir it into the soup.
Add butter and season with pepper before serving.

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
- Celery
- Provides the main flavor and body of the soup as it is cooked and strained.
- Flour
- Thickens the soup as it heats, giving it a smoother, creamier texture.
- Milk
- Adds richness and a creamy body to the thinned celery stock.
- Butter
- Adds fat for a rounder flavor and smoother mouthfeel.
The step that matters
Mixing the flour into the soup. Flour added dry or in lumps will clump and stay grainy. Mixing it into a smooth paste with a little water first lets it disperse evenly so the soup thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (celery, flour, milk, pepper, butter):
- Carrotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against celery, flour, milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
