Mayonnaise Sauce

Ingredients

Directions

  1. Separate the yolks from the whites of the eggs, placing the yolks in a basin.

  2. Add the mustard, salt, sugar, and cayenne to the yolks and mix well with a wooden spoon.

  3. Slowly add the oil drop by drop, stirring continuously in one direction until the mixture thickens to the consistency of butter.

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

What each ingredient does

Eggs
Egg yolks emulsify the oil and vinegar, giving the mayonnaise its thick body.
Salad oil
Forms the fat phase that, dispersed into the yolks, thickens the sauce.
Mustard
Its natural emulsifiers help hold the oil and water phases together.

The step that matters

Adding the oil. Oil must go in drop by drop while stirring constantly. Adding it too fast overwhelms the yolk's emulsifying capacity, so the droplets cannot be held in suspension and the mixture breaks and separates instead of thickening.

Swap the mustard

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

  1. Mustardthe original
  2. Capsicumfits about as well
  3. Shallotfits less well
  4. Asparagusfits less well

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