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

What each ingredient does

Eggs
Thicken the sauce as they set and give it a rich, smooth body.
Soft mild cheese
Melts into the sauce to provide the main flavor and creamy texture.
Cream or milk
Adds moisture so the cheese melts smoothly into a pourable sauce.
Butter
Adds fat that helps the sauce melt smoothly and carries flavor.

The step that matters

Stir the mixture until the cheese is melted. Cheese proteins toughen and separate when overheated, so keep the heat gentle and stir steadily. Eggs can scramble if the heat is too high, leaving the sauce grainy.

Swap the mustard

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

  1. Potatofits better
  2. Capsicumfits about as well
  3. Asparagusfits about as well
  4. Mustardthe original

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