Why it works: Lettuce and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 425 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Plain Salad-Dressing
Ingredients
Directions
Prepare the leaves
Remove the leaves from the stalk of the lettuce, discarding bruised or discolored ones.
Wash the clean leaves in a basin and drain thoroughly on a sieve.
Toss the leaves in a cloth to remove any remaining water.
Dress the salad
Place the dry leaves in a bowl and have an assistant sprinkle oil over them while you stir with a wooden spoon and fork.
Once the leaves are coated in oil, add a few drops of tarragon vinegar while continuing to stir.
Dust the salad with coarse sea salt and freshly ground black pepper, ensuring even distribution.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce leaves
- Form the body of the salad, carrying the dressing on their surfaces.
- Finest oil
- Coats the leaves, adding a smooth mouthfeel and carrying flavour.
- Tarragon vinegar
- Adds a sharp acidity that brightens the oil and leaves.
The step that matters
Drying the leaves before dressing. Oil does not mix with water, so any water left on the leaves stops the oil from coating them evenly and dilutes the vinaigrette's flavour. Thorough drying lets the oil cling to the leaf surfaces.
