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
- Cucumber
- Forms the main body of the dish and becomes tender when stewed.
- Onion
- Adds savory sweetness and aroma as it browns in the butter.
- Butter
- Browns the vegetables when fried and enriches the finished sauce with fat.
- Flour
- Thickens the gravy when cooked with butter, giving it body.
The step that matters
Drain the fried cucumber and onion. Draining on paper removes excess surface butter, so the finished gravy is not greasy and thickens properly.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, onion, butter, mace, flour):
- Nutmegfits better
- Capersfits better
- Turmericfits better
- White pepperthe original
Fit is the average pairing score against cucumber, onion, butter, mace, flour. Candidates are from the same food group and used in at least 100 recipes.
