Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Adds richness and a creamy body to the dressing.
- Egg
- Thickens the dressing as it cooks, giving it body.
- Flour
- Stabilises the cooked dressing so it thickens smoothly without splitting.
- Vinegar
- Provides the sharp acidity that flavours the dressing.
- Sugar
- Balances the vinegar's sharpness with sweetness.
- Cold cooked beans
- Form the body of the salad, absorbing the dressing.
The step that matters
Add the egg mixture to the boiling vinegar mixture. Egg proteins can scramble if the mixture is overheated or added too quickly. Adding it gradually while stirring and cooking gently lets the egg and flour thicken the dressing smoothly.
