Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their fat and emulsifying lecithin help bind the mustard, butter and cream into a smooth dressing.
- Melted butter
- Adds richness and fat, giving the dressing a silky mouthfeel.
- Cream
- Provides fat and moisture, thinning the base into a creamy, pourable texture.
- Mixed mustard
- Adds sharpness and helps stabilise the emulsion so it stays smooth.
- Horseradish
- Contributes a sharp, pungent heat that cuts through the richness of the cream and butter.
The step that matters
Add the butter gradually. Adding melted butter slowly to the yolk and mustard lets the emulsion form. Adding it too fast can split the dressing into greasy separated layers.
