Clean, rinse and dry the trout. Season inside and out with salt and pepper, turn in flour to the other side. Roast trout in hot oil over medium heat for 5-6 min. on each side.
Peel vegetable onion/garlic. Halve onion, cut into half rings, slice garlic.
Boil water with lemon peel, the onion rings, garlic, 1-2 tsp. salt (if preparing with 1 kg of trout), sugar, bay leaf, coriander and pepper and make 10 min. over medium heat. Pluck parsley.
Vinegar to the broth form, bring to a boil. Add the parsley, perhaps seasoning. Place the trout in the hot broth, allow to marinate for at least 12 hours.
Go well with it: Roast potatoes
Tip: If you don’t like coriander, you can leave it out.
