Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp acidity that defines the vinaigrette's flavour.
- Egg yolks
- Thicken the mixture as they set with gentle heat, giving body and richness.
- Butter
- Adds fat and smoothness, rounding out the sharpness of the vinegar.
- Heavy cream
- Adds moisture and a light, airy richness when folded in whipped.
- Mustard
- Adds sharp flavour and helps emulsify the rich mixture.
The step that matters
Remove from heat as it thickens. Egg yolks set quickly when heated. Taking the mixture off the heat as it thickens prevents it from curdling or scrambling, keeping it smooth.
Swap the mustard
