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

What each ingredient does

Egg yolks
Emulsify the oil and thicken the sauce into a smooth, rich body.
Oil (in the method)
Forms the bulk of the emulsion, giving the sauce its richness and body.
Vinegar
Adds acidity that sharpens flavour and helps balance the richness of the oil.
Mustard
Adds pungency and helps stabilise the emulsion.

The step that matters

Stir in the oil very slowly. Oil must be added gradually to the yolks so each droplet is coated and dispersed. Adding it too fast breaks the emulsion, so the sauce separates and turns greasy instead of thick and smooth.

Flavor stand-ins for the white pepper

How well each one fits the dish's main ingredients (sugar, vinegar, mustard, onion, parsley, egg):

  1. Capersbetter flavor fit
  2. Tarragonbetter flavor fit
  3. Dillbetter flavor fit
  4. White pepperthe original

Fit is the average pairing score against sugar, vinegar, mustard, onion, parsley, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
