Peel the potato and cut in half lengthways. In the vegetable stock, cook the potatoes fork-proof (do not overcook). Drain the water and let the potatoes cool slightly.
Warm the butter with the chives and salt. Briefly toss the potatoes in it.
Sauce:
Cut the shallots into thin slices. Chop the garlic.
Put both in a saucepan, pour wine and vermouth over them and bring to the boil. Add the thyme and pour in the stock. Let everything boil down for about 20 minutes.
Add the cream while stirring. Let simmer for another 15 minutes over medium heat. Season to taste with sugar, salt and pepper.
Fish:
Rinse the gutted and scaled fish again with water and pat dry. Cut the fish at an angle 3 times on both sides.
Salt the insides and stick rosemary and parsley in the abdominal cavity. Salt the outside of the fish and dust one side with flour.
Heat the lard and oil well in a large pan.
First fry the fish on the floured side for approx. 4-5 minutes until browned. Turn the fish over and cook for 5 minutes on a low heat.
Serving:
Put the sauce on preheated plates. Place the fish and potatoes. Garnish with lime and parsley.

Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
