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

What each ingredient does

Eggs
Egg yolk lecithin emulsifies the oil and water so the sauce holds together and becomes thick.
Olive oil
Forms the fat phase that gives the dressing its rich body and creamy texture.
Made mustard
Its natural emulsifiers help stabilise the emulsion and add a sharp, tangy flavour.

The step that matters

Adding the olive oil. Oil must be added drop by drop while stirring in one direction so tiny droplets disperse evenly. Adding it too fast overwhelms the egg's emulsifiers, causing the sauce to break or curdle.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (olive, mustard, egg, white pepper, vinegar, butter):

  1. Lemonthe original
  2. Avocadofits about as well
  3. Cherryfits less well
  4. Coconutfits less well

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