Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk and structure of the salad, holding their shape when sliced and layered.
- Egg yolks
- Thicken the dressing as they set with gentle heat and help bind it together.
- Whipped cream
- Adds richness and a light, airy texture to the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the eggs and cream.
- Mustard
- Adds sharpness and helps emulsify the dressing so it stays smooth.
- Shredded cabbage
- Adds crisp texture and a fresh, mild crunch to the salad.
The step that matters
Stir the egg yolk mixture over low heat until thickened. Egg proteins set at gentle heat, so low heat thickens the custard smoothly. Higher heat can scramble the yolks into lumps that cannot be fixed.
