Gut and fillet the trout. Batter the pieces of the fish in the flour and put them in the fry pan-you have boil up some olive oil there at first- with their skin downwards. Then turn the fish fillets on the other side, add some onion, increase the heat and leave it there for 3-4 minutes. Pour the basil leaves in a blender along with the parmesan cheese and the almonds. In another fry pan boil up some olive oil and in the same time wash some potatoes very well and trim them with their zest. Put the potatoes in the fry pan, add some salt and pepper.
