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 into the dressing, giving it a thick, creamy body.
- Olive oil
- Provides fat and richness, forming the body of the emulsion with the yolks.
- Mustard
- Acts as an emulsifier that helps hold the oil and water-based liquid together.
- Sugar
- Adds a touch of sweetness that balances the sharpness of the mustard.
- Milk or thick cream
- Adds moisture and softens the texture of the finished dressing.
The step that matters
Slowly add the olive oil drop by drop while stirring continuously. Adding oil too fast overwhelms the egg yolks, so the emulsion breaks and the dressing separates into a greasy, watery mixture instead of thickening smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, olive, milk):
