Turbot
Ingredients
Directions
Prepare the fish
Thoroughly wash and cleanse the turbot.
Rub allegar over the fish to enhance firmness.
Place the fish belly up in a fish plate and cover tightly with a cloth.
Boil in hard water with plenty of salt and vinegar, skimming to prevent discoloration.
Add the fish only when the water is boiling, then drain it when cooked.
Carefully remove the cloth and transfer the fish to a serving dish.
Make the sauce and finish
For the sauce, combine thyme, parsley, sweet herbs, and sliced onion in a stew-pan.
Lay the fish on top and sprinkle with herbs, chives, and sweet basil.
Cover with white wine and vinegar, adding bay salt and whole pepper.
Gradually increase the heat and cook until done, then remove from heat and let the fish sit in the liquid.
In a separate saucepan, melt butter and add anchovies, capers, chives, pepper, salt, nutmeg, flour, vinegar, and water.
Shake the mixture over heat until combined, then pour over the fish to heat through.
Serve the turbot with sauce poured over it and extra sauce in a boat, garnished with horseradish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turbot
- Forms the firm, flaky main body of the dish that holds its shape during poaching.
- Butter
- Melts into the sauce to add richness and a smooth, creamy texture.
- Anchovies
- Add a salty, savoury depth to the sauce that rounds out the butter.
- Capers
- Add a sharp, briny acidity that cuts through the richness of the butter.
- Flour
- Thickens the butter and liquid into a smooth, cohesive sauce.
- White wine
- Adds acidity and aroma to the cooking liquid, flavouring the fish as it cooks.
The step that matters
Boil in hard water with plenty of salt and vinegar, skimming to prevent discoloration.. Fish added to boiling water firms quickly and keeps its shape, while skimming removes foam and impurities that would otherwise cloud the surface and discolour the flesh.
Swap the onion
