Ingredients
Directions
Beat the yolks of two raw eggs with 1 teaspoon of mustard mixed with water.
Slowly add olive oil drop by drop while stirring constantly until thick.
Mix in 2 teaspoons of powdered sugar and ¼ teaspoon of salt.
Squeeze in the juice of 1 lemon and beat well.
If too thick, thin with a little sweet cream or omit lemon and cream and use vinegar instead.

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 into a thick, smooth dressing.
- Olive oil
- Provides the fat that gives the dressing its body and richness.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the oil.
- Powdered sugar
- Adds a little sweetness that softens the sharpness of the lemon.
The step that matters
Adding the olive oil. Oil must be added slowly, drop by drop, while stirring constantly. The egg yolk lecithin needs time to surround the oil droplets; adding oil too fast breaks the emulsion so it separates and stays runny.
Swap the mustard
How well each one fits the dish's main ingredients (egg, olive, sugar, lemon, cream):
- Spinachfits better
- Asparagusfits better
- Capsicumfits better
- Mustardthe original
Fit is the average pairing score against egg, olive, sugar, lemon, cream. Candidates are from the same food group and used in at least 100 recipes.
