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

What each ingredient does

Butter
Enriches the sauce with fat and flavour while forming the base for the roux.
Flour
Thickens the sauce when cooked with butter, giving it body and a smooth texture.
Milk
Forms the liquid of the sauce, which thickens as the starch in the flour swells with heat.
Onions
Add sweetness and aroma when softened, flavouring the sauce for the optional onion version.

The step that matters

Gradually add the milk, stirring constantly. Adding milk slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly instead of forming lumps. Starch swells as it heats in the liquid, which is what thickens the sauce.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (butter, flour, milk, pepper, sauce):

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

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