Why it works: Sugar and vinegar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 20,806 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Sweet-sour Dressing for Lettuce
Ingredients
Directions
In a bowl, combine sugar, eggs, vinegar, water, butter, and salt.
Boil the mixture for 3 minutes, stirring carefully.
Allow to cool, and if the dressing is too thick, thin it with sweet or sour cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the dressing as their proteins cook.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Provides the sour note and acidity that defines the dressing.
- Butter
- Adds richness and a smoother, rounder mouthfeel.
The step that matters
Boiling the mixture. Eggs thicken as their proteins set, but if the mixture overheats or is not stirred, the eggs can scramble and form lumps. Stirring carefully keeps the heat even so the dressing becomes smooth and thick.
