Why it works: Cucumber and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 6,050 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Flour and butter 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
- Cucumbers
- Provide the main vegetable bulk, softening and turning tender-sweet when fried.
- Onion
- Adds sweetness and aroma as it softens and browns in the frying fat.
- Flour
- Coats the vegetables so they brown evenly and develop a golden crust when fried.
- Steak
- Serves as the main protein, browned by broiling for savory flavor.
- Butter
- Adds richness and a rounded flavor to the hot steak.
The step that matters
Fry the cucumbers and onion until golden. Frying over steady heat browns the flour coating, which gives a crisp golden crust. Too little heat leaves the vegetables soggy and greasy, while too much burns the flour before the cucumbers soften.

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