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

What each ingredient does

Egg yolks
Act as the emulsifier, holding the oil and vinegar together in a smooth, thick cream.
Olive oil
Supplies the fat that gives mayonnaise its rich body and mouthfeel.
Vinegar
Adds sharp acidity for flavor and helps keep the emulsion stable.

The step that matters

Adding the olive oil gradually. Egg yolk lecithin can only surround so many oil droplets at once. Adding oil slowly lets each droplet be coated and dispersed, forming a stable emulsion. Pouring it in too fast can make the mixture break and separate into oily liquid.

Swap the spinach

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

  1. Capsicumfits better
  2. Cucumberfits about as well
  3. Tomatofits about as well
  4. Spinachthe original

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