Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanuts (in the method)
- Form the body of the soup and give it its main nutty flavour.
- Butter
- Adds richness and fat, carrying flavour through the soup.
- Flour
- Thickens the soup when cooked with the melted butter.
- Milk
- Adds creaminess and smoothness to the soup.
The step that matters
Stirring in the butter and flour mixture. Cooking flour in fat before adding it helps prevent lumps and gives a smooth, evenly thickened soup. Stirring steadily as it goes in keeps it from clumping.
Swap the celery
How well each one fits the dish's main ingredients (milk, butter, onion, flour):
- Cinnamonfits better
- Capersfits better
- Garlicfits better
- Celerythe original
Fit is the average pairing score against milk, butter, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
