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

What each ingredient does

Onions
Cooked down in butter to become sweet and form the base of the sauce.
Flour
Thickens the butter and onion mixture into a sauce when cooked with the liquid.
Milk
Liquid that, once reduced, forms the creamy body of the sauce.
Hard-boiled eggs
Main protein, held in the sauce to give the dish its body and substance.

The step that matters

Gently mix in the quartered hard-boiled eggs without breaking them. Hard-boiled egg whites are tender and break apart under rough stirring, leaving ragged pieces in the sauce. Folding gently keeps the quarters intact and the dish looking neat.

Swap the onion

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

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

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