Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Provides the bulk of the fat that forms the body and rich texture of the emulsion.
- Vinegar or lemon juice
- Adds acidity that balances the richness and helps keep the emulsion stable.
- Egg yolk
- Contains lecithin, an emulsifier that holds oil and water-based liquid together as a smooth sauce.
- Cream
- Adds moisture and softness, giving the sauce a milder, looser texture.
The step that matters
Blend the oil in while the yolk is emulsifying. Oil must be added slowly while mixing so droplets are dispersed and surrounded by yolk lecithin. Adding it too fast breaks the emulsion, leaving the sauce thin and oily instead of thick.
