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 ↓
Steak and Onions Fried
Ingredients
Directions
Prepare
Slice the onions into rings and soak them in cold water for 1 hour to reduce their strong flavor.
Fry the steak and onions
Heat the suet or dripping in a large frying pan.
Add the steak, which should be ½ inch thick, and fry on moderate heat.
Turn the steak often and cook for about 8 minutes until firm to the touch.
Drain the onions and add them to the pan, cooking until they are soft.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Its protein firms and browns in the hot fat, forming the main body of the dish.
- Suet or dripping
- Provides the frying fat that conducts heat evenly and browns the steak and onions.
- Onions
- Soften and sweeten as they cook, adding mellow flavor that balances the meat.
The step that matters
Drain the onions before adding them to the pan. Water clinging to the soaked onions turns to steam in hot fat and causes spattering. Draining them well lets the onions fry and soften instead of steaming.
Swap the onion
How well each one fits the dish's main ingredients (ketchup, flour, pepper):
- Capsicumfits better
- Horseradishfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against ketchup, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
