Turbot, with White Sauce
Ingredients
Directions
Poach the turbot
Place fresh herbs in a stewpan and lay the turbot on top.
Sprinkle with more herbs, salt, pepper, and the cut leek.
Cover the fish with equal parts vinegar and white wine.
Boil over moderate heat until the fish is cooked through.
Make the white sauce
In the meantime, melt the butter in a separate pan.
Add the anchovies, capers, shredded leeks, salt, pepper, nutmeg, a little vinegar, and water.
Stir constantly until heated through and slightly thickened.
Serve
Serve the turbot on a plate and pour the sauce over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted butter forms the rich base of the sauce, giving it body and a smooth, silky mouthfeel.
- Anchovies
- Dissolve into the warm butter, adding savoury depth to the sauce.
- Capers
- Add a sharp, briny acidity that cuts through the richness of the butter.
- White wine
- Along with vinegar, acidifies the poaching liquid, gently flavouring the fish as it cooks.
- Leeks
- Add mild onion-like aroma to the poaching liquid and the sauce.
The step that matters
Stir the sauce constantly as it heats. Butter and egg-free emulsions can separate or scorch if heated unevenly or left unattended. Constant stirring over gentle heat keeps the butter-based sauce smooth and lightly thickened rather than broken or burnt.
