If you plan to visit one of the attractions of Scandinavia, a special treat is smoked salmon. Food has been smoked by humans since ancient times. Originally this was done with the aim of preserving the product of the fishery to allow it to be consumed at a later date. In recent times, the processes of fish were carried out by means of refrigeration and freezing, so that the smoking of fish was carried out mainly with the aim of imparting a certain flavor and aroma during smoking.
