Dry the fish fillets, season with salt, pepper and drizzle with lemon. Turn in a little flour and fry on all sides in hot oil. Continue cooking in the preheated oven at 150 ° C; 10-15 minutes depending on the thickness of the fillets. Catfish is a very firm fish that can withstand a little temperature.
Pour Prosecco and vegetable broth on the roast residue and reduce to just under half. The finely chopped herbs - the amount is variable, I use 1/2 bunch each - and the pink berries, as well as some grated lemon zest. Finally stir in the crème fraîche and season with a pinch of nutmeg and, if necessary, a little salt.
Serve the fish fillets with the sauce and, for example, rice as a side dish. The dish is also suitable as a starter in a menu, with Prosecco as an accompaniment.
