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

What each ingredient does

Eggs
Thicken as they cook over heat, giving the mayonnaise its body and structure.
Olive oil
Provides the fat that, emulsified into the egg, makes the sauce rich and creamy.
Vinegar
Adds acidity that sharpens flavor and helps keep the sauce stable.
Thick cream
Adds richness and a soft, smooth texture when folded in at the end.

The step that matters

Gradually add the olive oil, vinegar, and lemon juice, stirring constantly. Adding the liquids slowly while stirring lets the oil disperse into the warm egg mixture as tiny droplets. Adding them too fast can make the sauce separate or curdle.

Swap the lemon

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

  2. Avocadofits about as well
  3. Cherryfits about as well

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