Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and give it its body.
- Eggs
- Chopped hard-boiled eggs add texture; beaten eggs thicken the vinegar dressing.
- Vinegar
- Provides acidity that gives the dressing its sharp, tangy flavor.
- Green onions
- Add mild, fresh onion flavor and a bit of crunch.
The step that matters
Stirring the beaten eggs into the hot vinegar. Egg proteins thicken when heated, but if the mixture gets too hot or is stirred poorly, the eggs can scramble into lumps. Stirring constantly while adding them keeps the dressing smooth.
