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

What each ingredient does

Eggs
Whole egg and whites build a beaten, ropey foam, while the cooked yolks help bind the oil into the dressing.
Olive oil
Supplies the fat that gives the dressing its body, richness and smooth mouthfeel.
Mustard
Its natural gums help stabilize the emulsion so the oil stays suspended in the dressing.
Vinegar
Adds acidity that brightens the flavor and balances the richness of the oil.
Sweet cream
Adds richness and moisture, softening the dressing's texture.

The step that matters

Gradually add the olive oil while beating. Oil must be added slowly so each drop is broken into tiny droplets and absorbed by the egg. Adding it too fast can overwhelm the egg, so the emulsion breaks and the dressing separates.

Swap the mustard

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

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

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