The process involves preserving and flavoring fish through extended exposure to smoke at temperatures typically below 80F (27C). This method differentiates itself from hot smoking, which cooks the fish, by focusing solely on imparting smoky flavor and extending shelf life without significant protein coagulation. For example, lox, a form of cured salmon, often undergoes a cold smoking process to achieve its characteristic texture and flavor profile.
This preservation technique offers several advantages, primarily in extending the consumable period of the fish. Beyond preservation, it imparts a distinct and desirable smoky flavor highly valued in culinary applications. Historically, communities relied on smoking as a vital method for food preservation, particularly in regions with limited access to refrigeration. This ensured a stable food supply throughout leaner months and allowed for trade and transportation of preserved goods.
