Ingredients
Directions
Make the emulsion
In a bowl, beat the egg yolks, mustard, sugar, and salt until very light.
Gradually add a few drops of oil at a time until the dressing thickens.

Finish and chill
Stir in the lemon juice, whipped cream, and cayenne pepper.
Chill the dressing in the refrigerator until ready to use.

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 vinegar so the dressing thickens and holds together.
- Oil
- Provides the fat that, dispersed into the yolks, builds the thick body of the dressing.
- Vinegar
- Adds acidity that balances the richness of the oil and yolks.
- Whipped cream
- Adds air and fat that soften the texture and lighten the dressing.
- Mustard
- Helps stabilize the emulsion by binding oil and water-based liquids together.
The step that matters
Adding the oil gradually. Oil must be added a few drops at a time at first so it disperses into the yolks as tiny droplets. Adding it too fast overwhelms the yolks, and the emulsion breaks into a thin, oily liquid that will not thicken.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
