Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Mashed yolks and whites form the thick body of the dressing.
- Melted butter or salad oil
- Adds fat that makes the dressing smooth and rich.
- Mixed mustard
- Adds sharpness and helps emulsify the fat into the mixture.
- Thick sweet cream
- Adds moisture and creaminess to loosen the egg paste.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness.
The step that matters
Add vinegar gradually to achieve a creamy paste consistency.. Vinegar thins and sharpens the mixture, so adding it slowly lets you stop once the dressing is creamy. Too much at once can make it watery and thin.
Swap the mustard
