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 ↓
Cream of Cucumbers
Ingredients
Directions
Make the soup base
In a pot, combine mutton stock, celery, onions, and cucumbers.
Boil until tender.
Mash the mixture through a fine sieve.
Make the cream
In a separate pan, melt butter and stir in flour to create a roux.
Gradually add 1 quart of milk to the roux, stirring until thickened.
Combine the thickened milk with the mashed cucumber mixture and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with flour to form a roux, giving the cream a smooth, rich body.
- Flour
- Thickens the milk when cooked with butter, giving the soup a creamy texture.
- Milk
- Forms the creamy base that thickens with the roux and mellows the soup.
- Cucumbers
- Provide the main flavor and, once mashed, the body of the soup.
The step that matters
Gradually add the milk to the roux. Adding cold milk all at once can leave lumps of flour. Adding it slowly while stirring lets the starch disperse evenly and thicken into a smooth sauce.
Swap the cucumber
How well each one fits the dish's main ingredients (mutton, celery, onion, butter, flour, milk):
- Leekfits better

- Cucumberthe original
Fit is the average pairing score against mutton, celery, onion, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
