Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Steak
Ingredients
Directions
Prepare
Preheat a gridiron over bright coals or heat a frying pan.
Butter the beef and beat it well without cutting.
Have a hot plate ready to catch the juices.
For onion flavor, slice 1-2 onions and fry them until brown before adding the steak.
Cook the steak
Cook the beef for 10-12 minutes, turning often to retain juices.
Add butter to the pan to prevent scorching and season with salt and pepper.
Make the gravy
For gravy, add a heaping spoonful of butter and stir in a level spoonful of dry flour.
Let it brown, then pour in hot water and pour over the steak.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tender beef
- Provides the meat that is cooked and served as the main dish.
- Butter
- Adds fat that prevents scorching and carries flavor in the pan and gravy.
- Dry flour
- Thickens the gravy and helps it brown when cooked in butter.
The step that matters
Letting the flour brown in the butter before adding water. Cooking the flour in fat until it browns builds a nutty flavor and removes raw starch taste. Adding water too early leaves the gravy pasty and bland.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, butter, pepper, coffee, flour):
- Potatofits better
- Capsicumfits about as well
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against beef, butter, pepper, coffee, flour. Candidates are from the same food group and used in at least 100 recipes.
