Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Adds richness and a creamy body to the dressing.
- Eggs
- Thicken the dressing as they cook and set in the hot mixture.
- Vinegar
- Adds acidity that gives the dressing a sharp, tangy flavour.
- Cabbage
- Forms the base of the salad and absorbs the warm dressing.
The step that matters
Letting the egg mixture come to a boil. Eggs thicken as they heat, but overheating can curdle them into lumps. Bringing the mixture to a boil while stirring is needed to cook the eggs enough to thicken the dressing.
