Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the butter and vinegar, thickening the dressing into a creamy texture.
- Butter
- Adds richness and fat, giving the dressing a smooth, rounded mouthfeel.
- Vinegar
- Provides acidity that sharpens flavour and helps thicken the egg yolks.
- Sugar
- Balances the acidity of the vinegar with sweetness.
- Mustard
- Adds sharp flavour and helps stabilise the emulsion.
The step that matters
Pour the hot mixture over the egg mixture and stir well. Pouring the hot butter and vinegar in while stirring constantly gently warms the egg yolks without scrambling them. Adding it too quickly or without stirring can cook the yolks into lumps.

Fit is the average pairing score against egg, sugar, pepper, cream, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
