Step by step

Five minutes from the end of the cooking time, add the salmon

Tips
Don't overcook the salmon: add it to your risotto towards the end of cooking. When grating the lemon zest be careful only to grate the yellow part of the lemon, not the white pith. Finally, let the risotto rest before serving: two minutes will be enough!
Trivia
Historically, smoking was a technique for preserving food, just like salting. Today it is used to give a lovely smokey flavour and aroma to foods.
