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

What each ingredient does

Egg yolks
Their lecithin emulsifies the oil and water so the sauce stays smooth and thick.
Olive oil
Forms the bulk of the sauce, providing richness and body once emulsified into the yolks.
Vinegar
Adds acidity that sharpens flavour and helps stabilise the emulsion.
Lemon juice
Adds bright acidity that balances the richness of the oil and yolks.

The step that matters

Adding the olive oil slowly. Oil must be dispersed into the yolks one drop at a time at first. Adding it too fast overwhelms the egg lecithin, so the emulsion breaks and the sauce turns runny and oily instead of thick.

Swap the mustard

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

  1. Capsicumfits better
  2. Spinachfits about as well
  3. Cucumberfits about as well
  4. Mustardthe original

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