Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White skinned onions
Form the main body of the dish and turn mildly sweet as they cook down.
Butter
Adds fat for richness and a smooth, rounded flavor.
Flour
Thickens the cooking liquid as its starch swells with heat.
Rich sweet milk
Adds liquid, creaminess, and body to the sauce around the onions.

The step that matters

Stirring the butter and flour into the onions. Flour clumps when it meets hot liquid unless it is well mixed with fat first and stirred in evenly. Stirring steadily while it goes in helps the starch thicken the liquid smoothly instead of forming lumps.

Swap the onion

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

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

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