Wash the salmon and dab dry. Cut into large cubes (approx. 60 g each). Wash lemons, grate dry and cut 1 lemon in half. Squeeze one half, cut the other half into slices.
Season salmon with salt and lemon juice. Add lemon slices to the salmon and cover with foil. Keep cold. Rub the zest off 1 lemon. Wash the coriander and shake dry. Pluck the leaves from the stalks, except some for garnishing, and chop finely.
Mix lemon zest and coriander, cover and set aside. Peel onion and garlic. Chop the onion finely. Chop garlic finely. Heat olive oil in a wide saucepan. Fry rice, onion and garlic in it until transparent.
Deglaze with wine. Add the hot broth gradually (by ladle) while stirring. As soon as the rice has absorbed the liquid, add the stock again. Proceed in this way until all the stock is used up.
The process takes about 20 minutes. Pull the pot off the stove. Add butter and parmesan and fold in carefully. Let it rest for 5 minutes. In the meantime heat oil in a pan and fry salmon all around for about 5 minutes until golden brown.
Cut 1/2 lemon into slices and fry for the last minute. Add lemon coriander to the risotto and fold in briefly. Arrange risotto and salmon. Garnish with lemon slices and sprinkle salmon with lemon pepper.
