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 base of the salad.
- Lucca oil
- Coats the leaves with fat, adding richness and carrying flavour.
- Tarragon vinegar
- Adds bright acidity and a distinct herbal aroma.
- Malt vinegar
- Adds sharp acidity and a malty, savoury tang.
The step that matters
Stir briskly after adding the vinegars. Vinegar is acidic and does not mix with oil on its own. Vigorous stirring disperses the vinegar into small droplets so it coats the leaves evenly rather than pooling at the bottom of the bowl, giving a balanced dressing in every bite.
Swap the lettuce
How well each one fits the dish's main ingredients (tarragon, vinegar, malt):
- Mustardfits better
- Shallotfits better
- Beetrootfits about as well
- Lettucethe original
Fit is the average pairing score against tarragon, vinegar, malt. Candidates are from the same food group and used in at least 100 recipes.
