Why it works: Lettuce and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Turbot Salad
Ingredients
Directions
Remove the flesh from the cooked turbot, discarding skin and bones. Cut the flesh into 1.5-inch square pieces.
Season the turbot pieces with pepper, coarse sea salt, olive oil, and vinegar. Cover and refrigerate until needed.
Wash and dry the lettuces thoroughly. Cut them into ½-inch wide pieces and leave in a cool place until needed.
In a bowl, beat the raw egg yolks for 2-3 minutes. Mix in the mustard, ½ teaspoon salt, and a little white pepper.
Gradually add 4 tablespoons of olive oil, beating well after each addition. Stir in 1 teaspoon of French vinegar and a few drops of tarragon vinegar.
Continue adding oil and vinegar in the same proportions until the sauce reaches a thick custard-like consistency. Refrigerate until needed.
To serve, layer the lettuce at the bottom of a dish, add a layer of turbot, and repeat until all ingredients are used.
Garnish with hard-boiled eggs, cucumber, beetroot, olives, and anchovies. Pour the sauce over the salad just before serving, adding a little sauce between layers of fish.
