Fiddlehead ferns are the young, coiled fronds of certain fern species, typically harvested in the spring. They are named for their resemblance to the scroll of a violin, or fiddle. These edible ferns are often found in damp, wooded areas and are a popular ingredient in various cuisines. Rich in nutrients, fiddlehead ferns are a good source of vitamins A and C, as well as omega-3 and omega-6 fatty acids. However, they should be cooked before consumption, as raw fiddleheads can contain toxins. They are often sautéed, steamed, or added to salads for a unique flavor and texture.
