Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing and bind it into a creamy emulsion as they cook.
- Flour
- Stabilizes the emulsion and adds body so the dressing thickens smoothly.
- Mustard
- Adds sharp flavor and helps emulsify the oil and milk.
- Vinegar
- Provides acidity that brightens the dressing and balances the richness.
- Oil
- Adds fat for a rich mouthfeel and smooth texture.
The step that matters
Heat in a double boiler until creamy. Egg proteins set gradually as they warm. Gentle, indirect heat lets the dressing thicken evenly; direct high heat can scramble the eggs and make the dressing grainy.
Swap the mustard
