Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp base of the salad and carries the dressing.
- Olive oil
- Adds fat and smooth body to the dressing, coating the leaves.
- Eggs
- Emulsify with the oil so the dressing holds together instead of separating.
- Rich cream
- Adds richness and softens the sharpness of the vinegar in the dressing.
- Tarragon vinegar
- Provides acidity and a sharp, aromatic flavour that brightens the salad.
- Cucumber
- Adds cool, moist crunch and a light fresh flavour.
The step that matters
Beat the oil and eggs until well combined. Oil and egg must be beaten thoroughly so the egg lecithin can emulsify the oil into droplets. If it is under-beaten, the oil separates from the dressing and pools instead of clinging to the leaves.
