Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beefsteak Smothered with Onions
Ingredients
Directions
Cook the steak
Broil the steak until cooked to your liking.
Cook the onions
Heat drippings or butter in a skillet and add the chopped onions.
Stir the onions until they are cooked through and avoid burning.
Assemble and serve
Place the cooked onions on top of the steak on a hot plate.
Cover with another hot plate for a few minutes to allow the steak to absorb the onion flavor.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Provides the main protein and meaty base that the onion flavor is absorbed into.
- Onions
- Add sweetness and savory aroma as they cook, flavoring the steak.
- Drippings or butter
- Fat for cooking the onions, carrying flavor and helping them brown and soften.
The step that matters
Stir the onions until cooked through without burning. Onions contain sugars that caramelize and turn bitter or acrid if scorched, while undercooked onions stay sharp and raw-tasting. Steady stirring over moderate heat cooks them evenly and develops sweetness.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper):

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