Why it works: Vinegar and lemon are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 7,334 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Sour Cream Dressing
Ingredients
Directions
Prepare
Chill the sour cream in the refrigerator for several hours.
Make the dressing
Using an electric mixer, beat the chilled cream until it forms stiff peaks.
Gradually add the vinegar, salt, cayenne, and lemon juice, mixing for an additional 2 minutes.

Cream and lemon barely smell alike, yet cooks put them together in 15,640 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Thick sour cream
- Provides fat and body, and thickens into stiff peaks when chilled and beaten.
- Vinegar
- Adds sharp acidity that brightens the dressing and balances the richness of the cream.
- Lemon juice
- Adds fresh acidity and aroma that sharpens the flavour of the dressing.
The step that matters
Beating the chilled cream to stiff peaks. Chilling firms the cream's fat so it can hold air and peaks. Beating too long can make the fat clump and turn grainy or buttery, so stop once stiff peaks form.

Fit is the average pairing score against cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
