Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Forms the bulk of the salad and gives it a meaty, substantial texture.
- Hard-boiled eggs
- Add body and a creamy texture when the yolks are mashed and blended into the dressing.
- Raw eggs
- Thicken the dressing as their proteins set with gentle heat, binding it together.
- Olive oil
- Adds fat and richness, and emulsifies into the yolk mixture to create a smooth, creamy dressing.
- Melted butter
- Contributes fat for richness and a smooth mouthfeel in the dressing.
- Lemon juice or vinegar
- Adds acidity that brightens the flavor and balances the richness of the eggs and fats.
The step that matters
Stir in the beaten raw eggs until thickened but not curdled. Raw egg proteins thicken the dressing as they gently set with heat. If the mixture gets too hot or is heated too fast, the proteins tighten and scramble, leaving lumps and a grainy texture instead of a smooth binder.
