  3. Add the mustard and mix thoroughly.

Emulsify

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

What each ingredient does

Egg yolks
Lecithin in the yolk emulsifies the oil and water, holding the sauce together as a stable mixture.
Olive oil
Forms the bulk of the sauce, giving it richness, body and its characteristic fat-based texture.
Lemon juice or vinegar
Adds acidity that brightens the flavour and helps stabilise the emulsion when it begins to break.
Prepared mustard
Its natural emulsifiers help bind the oil and yolk and add a sharp, savoury flavour.

The step that matters

Adding the oil slowly. Oil must be dispersed into tiny droplets before the yolk can coat them. Adding it too fast overwhelms the emulsifier, so the mixture breaks and curdles.

Swap the white pepper

How well each one fits the dish's main ingredients (egg, lemon, olive, mustard):

  1. Capersfits better
  2. Tarragonfits better
  3. Dillfits better
  4. White pepperthe original

Fit is the average pairing score against egg, lemon, olive, mustard. Candidates are from the same food group and used in at least 100 recipes.
