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

What each ingredient does

Egg yolks
Emulsify and thicken the sauce as they set gently with heat.
Butter
Adds richness and a smooth, silky mouthfeel to the sauce.
Vinegar
Provides sharp acidity that balances the richness of the yolks and butter.
Prepared mustard
Adds sharp flavour and helps stabilise the emulsion.

The step that matters

Heating the egg yolk mixture. Egg yolks thicken as their proteins set with gentle heat, but overheating scrambles them and causes curdling. Heat only until just below boiling and remove from the heat immediately to keep the sauce smooth.

Swap the mustard

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

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

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