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

What each ingredient does

Eggs
Beaten eggs thicken the sauce as they heat and set.
Butter
Adds fat and richness to the sauce.
Milk
Forms the liquid base of the sauce.
Vinegar
Adds acidity that sharpens the dressing's flavor.
Sugar
Adds sweetness to balance the vinegar.
Mustard
Adds sharp, savory flavor.

The step that matters

Stirring the egg mixture into the boiling sauce. Egg proteins set with heat, so adding the eggs to very hot liquid without constant stirring can leave lumps or scrambled bits. Stirring keeps the eggs dispersed so the sauce thickens smoothly.

Swap the mustard

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

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

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