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 through methods like air drying or using a dehydrator. 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.
