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

What each ingredient does

Egg yolk
Emulsifies the oil and water in the vinegar, giving the sauce its thick, creamy body.
Salad oil
Forms the bulk of the sauce, giving it richness and a smooth texture when emulsified.
Vinegar
Adds acidity that brightens the rich oil and balances the flavour.
Shallots
Contribute a mild, sharp onion flavour and aroma throughout the sauce.
Gherkins
Add sourness, crunch and a tangy bite to the sauce.

The step that matters

Adding the oil gradually. Egg yolk can only hold a limited amount of oil before the emulsion breaks. Adding oil in drops at first, and beating well after each addition, lets the lecithin in the yolk coat the droplets so the sauce stays thick and smooth instead of separating.

Swap the mustard

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

  1. Chivefits better
  2. Lettucefits about as well
  3. Mustardthe original
  4. Beetrootfits about as well

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