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

What each ingredient does

Hard-boiled egg yolks
Form the creamy base that the oil emulsifies into.
Oil
Adds richness and a smooth, creamy texture as it emulsifies with the yolks.
Mustard
Its natural emulsifiers help hold the oil and yolk mixture together.
Vinegar
Adds acidity that brightens the rich yolk and oil flavor.

The step that matters

Adding the oil gradually. Oil added too fast cannot be absorbed by the yolk mixture and can separate, leaving a greasy, broken texture. Adding it slowly while mixing lets the yolk lecithin coat the oil droplets and form a stable, uniform emulsion.

Swap the onion

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

  1. Horseradishfits better
  2. Shallotfits better
  3. Capsicumfits better
  4. Onionthe original

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