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 ↓
Beef Steaks Slewed with Cucumber
Ingredients
Directions
Prepare the cucumbers and onions
Pare the cucumbers and cut them into slices about an inch long.
In a stewpan, add the cucumbers, sliced onions, and butter. Fry until brown.
Add the gravy and dust in a little flour.
When the cucumbers are tender, skim off the fat.
Cook and serve
Season the rump steaks with white pepper and salt, then fry quickly in butter.
Place the cooked steaks in a dish and pour the cucumbers, onions, and gravy over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Soften during slow cooking and form the bulk of the vegetable sauce.
- Onions
- Brown in butter to add sweetness and savory depth to the sauce.
- Gravy
- Provides the liquid base that carries the flavor of the sauce.
- Flour
- Thickens the gravy so the sauce clings to the steaks.
- Rump steaks
- Form the main protein, seared quickly to brown the outside while staying tender.
The step that matters
Frying the steaks quickly. High heat browns the surface through the Maillard reaction, building flavor. Overcooking toughens the meat, so the steaks should be fried briefly and kept tender.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, onion, butter, flour):

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