Smoked salmon is a blanket term for salmon of any origin or cut that is cured with any kind of smoke. Hot smoked salmon is smoked basically like meat; resulting in a firm, flaky piece of fish. The flavor and texture of hot smoked salmon is similar to grilled salmon, with smoky undertones.  Cold-smoked salmon is smoked significantly longer and at a lower temperature than hot-smoked, which results in a texture that is similar to lox, but with an infused smoky flavor.
