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 enrich its texture as they cook with the vinegar.
- Heavy cream
- Adds richness and a light, airy texture when folded into the cooled dressing.
- Flour
- Helps thicken the dressing so it holds together when cooked.
- Hard-cooked eggs
- Add body and a firm, chopped texture to the salad.
- Pickles
- Add acidity and a sharp contrast to the rich dressing.
- Mustard
- Adds sharp flavor that balances the richness of the dressing.
The step that matters
Thickening the dressing over boiling water. Hot vinegar must be added slowly while stirring, or the egg yolks can scramble and curdle. Gentle heat over boiling water lets the mixture thicken smoothly, and it should be cooled before folding into the cream so the cream does not deflate.
