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):
- Capsicumfits better
- Shallotfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against egg, olive, sugar, vinegar, mustard, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
