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 ↓

Ingredients
Directions

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
- Butter
- Adds richness and body to the soup as it melts into the liquid.
- Flour
- Thickens the soup when creamed with butter and stirred into the hot mixture.
- Milk
- Provides the creamy liquid base that gives the soup its smooth texture.
The step that matters
Adding the butter and flour mixture. If the butter and flour are added without being creamed smooth, lumps of raw flour can form and stay in the soup. Blending them into a paste first lets the flour disperse evenly so it thickens smoothly when stirred into the hot liquid.
Swap the onion
How well each one fits the dish's main ingredients (milk, pepper, celery, butter, flour):
- Carrotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against milk, pepper, celery, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
