Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter lettuce
- Forms the tender, delicate body of the salad.
- Wine vinegar
- Provides acidity that sharpens the dressing and balances the oil.
- Dijon mustard
- Acts as an emulsifier, helping the oil and vinegar stay combined.
- Minced shallots
- Adds a mild, sharp onion-like aroma and flavour to the dressing.
- Oil
- Supplies fat that carries flavour and gives the dressing a smooth body.
The step that matters
Blend well. Vinegar and oil do not mix on their own. Thorough blending with mustard creates a temporary emulsion, so the dressing coats leaves evenly instead of separating into oily and sour pools.

Fit is the average pairing score against butter, lettuce, wine, vinegar, shallot. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
