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.

Swap the potato
