Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they set over heat, giving it a smooth, creamy body.
- Butter
- Adds richness and a smooth mouthfeel to the cooked dressing.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness.
- Sugar
- Adds sweetness that rounds out the sharp vinegar and mustard.
- Whipped cream
- Lightens the thickened dressing and adds a soft, airy texture.
The step that matters
Stirring over boiling water until thickened. Egg yolks thicken as they heat, but if they get too hot they can scramble into lumps. Stir gently and keep the bowl over simmering rather than furiously boiling water, so the dressing becomes smooth.
