Balik salmon is made by Caviar House and sold at all of their locations world-wide. Note that the price varies by location (sometimes quite significantly, I've seen over 100% higher prices at some locations than others for the same product). The curing process is secret and proprietary, and in 20 years of looking I have not found another source that is as good. Some come quite close and use higher quality fish. In USA/NYC you can try the smoked salmon sold mail-order by Ducasse, by no means the same but comparable.
