Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the main body of the dish, cooked through in the pan with the onions.
- Onions
- Add sweetness and aroma as they soften and brown in the pan juices.
- Flour
- Coats the steak, helping it brown and thickening the pan juices slightly.
- Lard
- Fat for frying that carries heat evenly and adds richness to the steak.
The step that matters
Turning everything over. The onions sit on the steak and can scorch against the hot pan before the steak cooks through. Turning at the midpoint, then watching the onions during the second five minutes, keeps them from burning.
Swap the onion
