Though the terms "smoked salmon" and "lox" are used interchangeably, they're in fact, not quite the same thing. Real lox (also called belly lox) refers to the midsection of a salmon that's simply been cured in a salt brine; consequently, it possesses a saltier flavor than what many of us associate with smoked salmon.
Part of the confusion arises from the use of the term "Nova lox" or "Nova salmon," which originally referred to the lightly cured and cold-smoked salmon that hailed from Nova Scotia.
Today, smoked salmon is often prepared using wild and farm-raised salmon from both the Atlantic as well as the Pacific — and modern-day usage of the term has further blurred the distinction between lox, Nova lox, and smoked salmon. Did you know the distinction between the two?
