In a bowl, mix the sugar, cornstarch, mustard, and yolks of the hard-boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw eggs
- Their proteins set when cooked, thickening the dressing into a creamy body.
- Hard-boiled egg yolks
- Add rich, smooth body and emulsify into the dressing for a silky texture.
- Cornstarch
- Thickens the liquid as it heats, giving the dressing body without extra eggs.
- Cream
- Adds moisture and richness, softening the sharpness of the vinegar.
- Vinegar
- Provides the acidity that gives the dressing its tangy flavor.
The step that matters
Pour the hot vinegar mixture slowly while stirring. Adding hot liquid to egg too quickly can scramble the eggs into lumps. Pouring slowly while stirring gradually warms the eggs so they blend smoothly before thickening.
