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 the body of the smothered sauce.
- Butter
- Adds fat and richness to the onions and the sauce.
- Flour
- Thickens the cooking liquid into a light gravy around the onions.
- Beef steak
- Provides the main protein, which becomes tender as it simmers in the onions.
The step that matters
Dredging the onions in flour. Flour added to hot onions can clump if not stirred in well. Stirring while the onions soften lets the starch disperse and thicken the liquid evenly.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, flour, beef):

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