Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken and emulsify the dressing as they set during gentle cooking.
- Cornstarch
- Thickens the liquid into a smooth, stable body as it heats.
- Vinegar
- Adds sharpness that balances the sweetness and richness of the dressing.
- Butter
- Adds richness and a smoother mouthfeel when stirred in off the heat.
- Sugar
- Balances the acidity of the vinegar with a mild sweetness.
The step that matters
Cook in a steamer while stirring until thickened. Eggs begin to set around moderate heat and can curdle if overheated or left unstirred. Gentle, constant stirring keeps the mixture smooth while the cornstarch thickens it.
Swap the mustard
