Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they cook, forming a moist bed that flavours the steak.
- Beef steak
- Provides the main protein; pounding thins it so it cooks through during simmering.
- Flour
- Dusted on each layer, it helps thicken the pan juices and lightly coat the meat.
The step that matters
Covering the pan tightly while simmering. A tight lid traps steam so the steak braises in moist heat and stays tender. If the lid is loose, liquid evaporates, the meat can dry out, and the flour may not thicken the juices properly.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, flour):

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