Why it works: Tarragon and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 602 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Lettuce Salad
Ingredients
Directions
Prepare the lettuce
Wash the lettuce if necessary.
Dry the lettuce thoroughly with a cloth.
Break or cut the leaves into convenient pieces using a silver knife.
Make the dressing
In a bowl, combine the yolks of the hard-boiled eggs, 2 teaspoons of dry mustard, pepper, and salt to taste, along with 1 tablespoon of oil, and mix until smooth.
Gradually add oil and vinegar to create a mayonnaise-like sauce.
Stir in the tarragon, minced eschalot, and diced egg whites.
Toss and serve
Add the lettuce and garden cress.
Mix everything thoroughly using a wooden or bone fork and spoon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks bind the oil and vinegar into a stable, creamy, mayonnaise-like sauce.
- Oil
- Adds fat and smooth body, coating the leaves and carrying the flavour of the dressing.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the oil and yolks.
- Dry mustard
- Helps emulsify the yolks and oil and adds a sharp, pungent note.
- Tarragon
- Contributes its distinctive aniseed-like aroma to the dressing.
- Eschalot
- Adds a mild, sharp onion-like flavour that lifts the dressing.
The step that matters
Adding the oil and vinegar gradually. Oil must be added slowly to the yolk mixture so its droplets are dispersed and emulsified. Adding it too fast makes the sauce split and stay thin and greasy instead of thick and creamy.
Swap the lettuce
