Wash the trouts thoroughly under water to remove the last traces of the guts.
On a wooden chopping board, sprinkle a handful of flour, and dip the trouts in them until they're covered with a thin layer of flour.
Pre-heat oven to 175°C.
Put about half the almonds in an ovenproof dish, then the trouts, then the rest of the almonds. Cook until the trouts are done (about 20-30 minutes depending on how large your fish are. Your fishmonger will probably know).
