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 proteins bind the cream and butter into a smooth, thick dressing.
- Melted butter
- Adds fat and richness, giving the dressing a smooth, mellow body.
- Sweet cream
- Supplies fat and moisture, and thickens into a rich, creamy texture when blended with the yolks.
- Mustard
- Its emulsifiers help hold the fat and liquid together and add a sharp, savory note.
- Vinegar
- Adds acidity that brightens the rich dressing and lets you adjust its thickness.
The step that matters
Gradually pour in the cream. Adding cream slowly lets the yolk and butter emulsion absorb it evenly. Pouring it all at once can break the emulsion, leaving the dressing thin and greasy instead of thick.
