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 and bind it into a smooth, creamy emulsion as they cook.
- Vinegar
- Adds acidity for a sharp flavour and helps set the egg yolks as they cook.
- Butter
- Adds richness and smoothness to the emulsified base.
- Cream
- Adds richness and a soft, creamy texture to the finished dressing.
The step that matters
Adding the vinegar to the yolks. Pour the hot vinegar slowly while stirring constantly. Adding it too fast can scramble the egg yolks, leaving lumps instead of a smooth, thickened dressing.
Swap the walnut
How well each one fits the dish's main ingredients (egg, mustard, sugar, butter, vinegar, cream):
