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, providing protein and substance that the sauce coats.
Butter
Adds fat and richness, carrying flavour as it cooks the onion.
Onion
Softens and sweetens as it fries, adding savoury depth to the sauce.
Flour
Thickens the milk into a smooth white sauce by gelatinising its starch.
Milk
Forms the liquid base of the sauce, adding moisture and creaminess.

The step that matters

Gradually add the milk, stirring until it forms a nice white sauce.. Adding milk slowly while stirring lets the flour disperse evenly and hydrate, preventing lumps. Continued stirring keeps the starch from clumping as the sauce thickens.

Swap the onion

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

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

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