Why it works: Butter and milk 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
- Cucumbers
- Form the main body of the soup and give it its fresh, mild flavour.
- Butter
- Fat that cooks the cucumbers gently and carries flavour.
- Flour
- Thickens the soup as it cooks with the stock.
- White stock iii
- Forms the liquid base of the soup.
- Milk
- Adds creaminess and softness to the soup.
- Egg yolks
- Enrich and thicken the soup when added near the end.
The step that matters
Adding cream and egg yolks after reheating. Egg yolks thicken when heated but can curdle or scramble if the soup is at a hard boil. Reheat gently and keep the soup just below boiling once the yolks and cream go in, so it stays smooth.
Swap the mace
How well each one fits the dish's main ingredients (cucumber, butter, flour, milk, onion, cream, egg):
- Capersfits better
- Nutmegfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against cucumber, butter, flour, milk, onion, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
