Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and water, letting the oil spread into tiny droplets for a thick, creamy texture.
- Olive oil
- Provides the fat that gives the dressing its richness and body as it emulsifies with the yolk.
- Mustard
- Helps stabilise the emulsion and adds sharpness that balances the richness of the oil.
The step that matters
Slowly stir in the olive oil. Adding oil too fast overwhelms the yolk, so it cannot break the oil into fine droplets and the mayonnaise may split into a greasy, separated liquid. Adding it slowly lets the emulsion form and thicken.
Swap the mustard
How well each one fits the dish's main ingredients (egg, olive, pepper):
