Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the salad, providing crisp, shredded body.
- Hard-boiled eggs
- Add richness and substance as a protein topping.
- Salad oil
- Coats the leaves, adding fat and a silky mouthfeel to the dressing.
- Tarragon vinegar
- Adds acidity that brightens the flavour and balances the oil.
The step that matters
Dissolve the salt in the vinegar before adding oil. Salt dissolves readily in acid but not in oil. Dissolving it in the vinegar first spreads the seasoning evenly, so the dressing tastes consistent instead of gritty or patchy.
