Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the bulk and mild, starchy body of the salad.
- Vinegar
- Adds the sharp acidity that defines the tangy dressing.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Eggs
- Thicken the dressing gently when stirred into warm liquid.
- Butter
- Adds richness and a smoother mouthfeel to the dressing.
- Mustard
- Adds a sharp, pungent note that cuts through the sweet-sour dressing.
The step that matters
Stir in the eggs off the heat, then heat gently. Beaten eggs thicken a warm dressing by gently setting their proteins. If the mixture is allowed to boil after the eggs go in, the proteins can tighten and curdle, leaving a grainy, uneven dressing instead of a smooth one.
Swap the beans
