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 their proteins set during gentle cooking, giving it body.
Dry mustard
Supplies the sharp, pungent heat that defines the sauce.
Sugar
Balances the mustard's bitterness and sharpness with sweetness.
Cider vinegar
Adds acidity that brightens the flavor and cuts the richness.
Butter
Adds fat that enriches the flavor and smooths the texture when beaten in.

The step that matters

Cook until thick. Egg proteins set over gentle heat, so a double boiler is used. If the heat is too high, the eggs can scramble and the sauce turns grainy instead of smooth and thick.

Swap the mustard

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

  1. Mustardthe original
  2. Capsicumfits about as well
  3. Cucumberfits less well
  4. Shallotfits less well

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