Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens as it cooks, giving the dressing a smooth, custard-like body.
- Sour cream
- Adds creaminess and a mild tang to the dressing.
- Vinegar
- Provides sharp acidity that brightens the dressing and balances its richness.
- Sugar
- Adds sweetness that rounds out the vinegar's sharpness.
The step that matters
Cook over medium heat, stirring constantly. Egg proteins set as they heat, so if the mixture gets too hot or isn't stirred, the egg can curdle or scramble instead of thickening smoothly. Constant stirring spreads the heat evenly and keeps the texture silky.
