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.
Olive oil
Provides the fat that gives the sauce its richness and body.
Vinegar
Adds acidity that brightens the sauce and balances the richness of the oil.
Mixed pickles
Contribute tangy, sharp flavour and texture through their chopped bits.

The step that matters

Stir in the olive oil very slowly. Egg yolks can only hold oil in suspension when it is added gradually. Pouring too fast breaks the emulsion, so the sauce separates and turns oily instead of thick and smooth.

Swap the onion

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