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 brown, forming the base of the sauce.
Butter
Fat that browns the onions and carries their flavor.
Flour
Thickens the hot water into a sauce as it cooks.
Beefsteak
Main protein, cooked by broiling and then finished by stewing in the sauce.

The step that matters

Place the beefsteak into the pan with the onions, cover tightly, and let it stew for about 5 minutes.. Flour thickens the sauce only when it is simmering, and covering the pan traps steam so the steak stays moist and heats through gently rather than drying out.

Swap the onion

How well each one fits the dish's main ingredients (butter, flour, pepper):

  1. Shallotfits better
  2. Chivefits better
  3. Capsicumfits better
  4. Onionthe original

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