Start by preheating your oven to 240 degrees. Season the fish with salt and pepper
And stuff it with fennel slices, lemon slices, bay leaf, dill, and rosemary.
In the meantime, prepare the salt by adding the egg whites and mixing it with your hands.
Prepare a large baking dish and cover it with ⅓ of the salt. Next, place the fish on top and cover it entirely with the prepared salt, making sure you press slightly, so the salt stays in place.
Bake at 240 degrees for 30 minutes, and after baking, let it rest for another 10 minutes before serving.
