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
Soak the sliced onions in cold water for 1 hour to reduce their strong flavor.
Heat the suet or dripping in a large frying pan over moderate heat.
Cook the steak and onions
Add the steak to the pan and fry, turning often, for about 8 minutes until firm to the touch.
Drain the onions and dry them with a towel, then add them to the pan with the steak if there is room, frying until lightly colored.
Make the sauce and serve
To make the sauce, sprinkle in the flour, add the ketchup, pepper, salt, and water, stirring until it boils.
Strain the sauce over the steak and serve with the onions around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Frying over moderate heat firms the meat and browns its surface, giving it flavor.
- Onions
- Frying softens them and browns their sugars, adding sweetness to the dish.
- Suet or dripping
- Provides fat for frying, carrying heat evenly and adding richness to the steak and onions.
- Flour
- Thickens the sauce as it heats with the liquid, giving it body.
The step that matters
Drying the onions before frying. Wet onions steam instead of browning in hot fat and can spatter. Patting them dry lets their surface brown lightly, which adds flavor.
Swap the onion
How well each one fits the dish's main ingredients (flour, ketchup, pepper):
- Capsicumfits better
- Horseradishfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against flour, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
