Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Provides creamy body and a mild tang that forms the base of the dressing.
- Sugar
- Adds sweetness to balance the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and cuts the richness of the sour cream.
- Mustard
- Adds a sharp, aromatic note and helps the dressing hold together.
The step that matters
Pour the dressing over the lettuce just before serving. Acidic dressing draws water out of lettuce through osmosis, so it wilts and loses crispness if dressed too early.
Swap the lettuce
How well each one fits the dish's main ingredients (cream, sugar, vinegar, mustard):
- Horseradishfits better
- Radishfits about as well
- Lettucethe original
- Shallotfits about as well
Fit is the average pairing score against cream, sugar, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
