Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil
- Forms the body of the dressing and carries flavor as a fat.
- Vinegar or lemon juice
- Adds acidity that brightens the dressing and balances the oil.
- Paprika
- Adds color and a mild, sweet, earthy aroma.
The step that matters
Slowly drizzle in the oil while stirring. Adding oil gradually while stirring helps it disperse into the acidic liquid as small droplets, so the dressing stays smoother and less likely to separate.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (vinegar, onion, tarragon):
- Mustardthe original
- Shallotfits about as well
- Chivefits less well
- Lettucefits less well
Fit is the average pairing score against vinegar, onion, tarragon. Candidates are from the same food group and used in at least 100 recipes.
