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

What each ingredient does

Eggs
Form the main body of the dish and set to a firm, tender texture when heated.
Flour
Thickens the butter and milk into a smooth, stable cream sauce.
Butter
Adds richness and fat, and helps the flour cook into the sauce base.
Milk
Forms the liquid of the cream sauce, giving it body and a creamy texture.
Onions
Add sweetness and savory flavor that complements the rich sauce.

The step that matters

Whisk in the milk until thickened. Milk added to a flour-and-butter roux must be whisked constantly as it heats; otherwise lumps form and the sauce may not thicken smoothly. Cooking the flour briefly first removes raw flour taste.

Swap the onion

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

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

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