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

What each ingredient does

Onions
Form the main body of the dish and soften into a tender, sweet base.
Milk
Forms the liquid base of the creamy sauce.
Butter
Adds fat and richness to the sauce.
All-purpose flour
Thickens the milk into a smooth, creamy sauce.

The step that matters

Stir the flour into a cream. Mixing flour with a little liquid before adding it to the hot mixture helps prevent lumps. Flour needs to be fully incorporated and brought to a boil so it thickens evenly and loses its raw starchy taste.

Swap the onion

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

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

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