Fermented fish products are traditional foods made by fermenting fish, which enhances their flavor and preserves them. This process involves the breakdown of fish proteins and fats by bacteria and enzymes, resulting in a unique taste and texture. Common examples include surströmming from Sweden and fisk sauce used in various Asian cuisines. These products are rich in nutrients, including omega-3 fatty acids and vitamins. Fermentation also helps to develop beneficial probiotics, which can aid digestion. Fermented fish products are enjoyed in many cultures and are often used in cooking or as condiments to enhance dishes.
