Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lettuce
Forms the crisp, leafy bulk of the salad.
Cress
Adds a peppery, fresh flavour and crisp texture to the greens.
Vinegar
Provides acidity that sharpens the dressing and balances the oil.
Salad oil
Adds fat that carries flavour and gives the dressing body.
Mustard
Emulsifies the oil and vinegar and adds a sharp, pungent note.

The step that matters

Gradually add the salad oil while mixing. Adding oil slowly while whisking breaks it into small droplets held in the vinegar, so the dressing stays emulsified and cohesive rather than separating into greasy layers.

Swap the lettuce

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