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 help bind the butter and vinegar into a smooth emulsion.
- Melted butter
- Adds fat for richness and a smooth, silky mouthfeel to the dressing.
- Vinegar
- Provides acidity that sharpens the flavor and balances the rich butter and yolks.
- Whipped cream
- Lightens the dressing and adds a soft, airy, creamy texture.
- Walnuts
- Add crunch, a slightly bitter note and fat that contrasts with the celery.
- Celery
- Contributes crisp texture and fresh, moist bulk to the salad.
The step that matters
Thickening the dressing over the double boiler. Egg yolks thicken as they warm, but if the heat is too high or stirring stops they can scramble. Adding the butter and vinegar gradually while stirring constantly keeps the mixture smooth and evenly thickened.
