Mayonnaise Dressing
Ingredients
Directions
Mix the yolks of two hard boiled eggs and one raw egg thoroughly with the salt.
Slowly beat in the olive oil, drop by drop, until well combined.
Season with cayenne pepper, mustard, onion, tarragon vinegar, and cider vinegar.
Alternate adding the vinegar with the oil to prevent the dressing from becoming too thin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and water so the dressing becomes thick and smooth.
- Olive oil
- Provides the fat that forms the body and richness of the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the rich oil.
The step that matters
Alternate adding the vinegar with the oil. Oil added too quickly can break the emulsion, and the dressing loses its thickness. Adding vinegar between additions of oil helps keep the emulsion stable and the dressing from thinning out.
Swap the onion
How well each one fits the dish's main ingredients (egg, olive, pepper, mustard, tarragon, vinegar, cider):
- Shallotfits better
- Lettucefits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against egg, olive, pepper, mustard, tarragon, vinegar, cider. Candidates are from the same food group and used in at least 100 recipes.
