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

What each ingredient does

Egg yolks
Emulsifiers that bind the oil and acid into a thick, stable dressing.
Mustard
Helps hold the oil and vinegar emulsion together and adds sharpness.
Oil
Forms the body of the dressing when slowly whisked into the yolks.
Lemon juice
Adds acidity that brightens the dressing and balances the richness of the oil.
Vinegar
Adds acidity that sharpens flavor and helps stabilize the emulsion.

The step that matters

Gradually add the oil, starting with a little, until fully incorporated.. Oil must be added slowly so tiny droplets disperse and are coated by egg yolk emulsifiers. Adding it too fast can break the emulsion, leaving a greasy, separated dressing.

Swap the lemon

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