Fish jerky is a type of dried fish that has been seasoned and preserved for long-term storage. It is made by marinating fresh fish in a mixture of salt, spices, and sometimes sugar, before drying it out using methods like air drying, smoking, or dehydrating. This process removes moisture, which helps prevent spoilage and enhances the flavor. Fish jerky is a popular snack due to its high protein content and portability. It can be made from various types of fish, including salmon, tuna, and cod. Many people enjoy it as a healthy alternative to traditional meat jerky.
