Wash the fish and pat dry, season with salt and pepper. Fry in the pan until cooked through, then remove and set aside.
Sweat the finely chopped onion and the squeezed garlic in the pan. Deglaze with white wine. When the alcohol has evaporated a little, add the cream and let it boil down for approx. 5-10 minutes. Finally add the herbs. I always use fresh ones from the garden, but dried ones are just as good.
Cut the fish into small pieces (it doesn`t matter if it disintegrates) and add to the sauce in the pan for another 5 minutes. Season to taste with salt and pepper.
