Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as they heat, thickening the dressing and giving it body.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Prepared mustard
- Adds sharp flavour and helps emulsify the fats, keeping the dressing smooth.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness.
- Fresh cream
- Adds richness and moisture, softening the texture of the dressing.
The step that matters
Cook over medium heat, stirring, until the mixture thickens. Egg proteins set at moderate temperatures. If the heat is too high or stirring stops, the eggs can scramble and curdle instead of thickening the dressing smoothly.
