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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Frying turns their exterior golden while the flour coating helps them brown and crisp.
- Onion
- Frying softens its sugars and browns them, adding sweetness alongside the cucumbers.
- Flour
- Dredging coats the vegetables so they brown more evenly and form a light crust when fried.
- Steak
- Broiling browns the surface directly, forming the main cooked element the vegetables are served over.
- Butter
- Melted into the hot dish, it adds fat and richness to the steak.
The step that matters
Fry the cucumbers and onion until golden. Cucumbers hold a lot of water, so if the pan is not hot enough or is crowded, they steam instead of browning. Frying in a hot pan in a single layer gives a golden, crisp surface.
