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 Stewed with Cucumber
Ingredients
Directions
Make the cucumber sauce
Pare and slice the cucumbers into 1-inch pieces.
In a stewpan, melt the butter and fry the cucumbers and sliced onions until brown.
Add the gravy and dust in the flour.
Cook until the cucumbers are tender, then skim off the fat.
Cook and serve the steaks
Season the steaks with white pepper and coarse sea salt, then fry them quickly in butter.
Place the cooked steaks in a dish and pour the cucumber mixture 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 stewing and form the bulk of the sauce, giving it body and a mild, tender texture.
- Onions
- Browned in butter, they add sweetness and savoury depth to the stewed sauce.
- Gravy
- Provides the liquid base of the sauce and carries the flavour of the stew.
- Flour
- Thickens the gravy as it cooks, giving the sauce a smooth, coating consistency.
- Rump steaks
- Main protein, seared quickly in butter to brown the outside and keep the inside tender.
The step that matters
Browning the cucumbers and onions. Frying until brown develops deep, savoury flavours through browning reactions. Pale vegetables make a flat sauce, so they should be coloured before the gravy goes in.
