What are fiddleheads?

Fiddleheads are the tightly coiled fronds of young ferns, specifically those of the ostrich fern (Matteuccia struthiopteris) and the lady fern (Athyrium filix-femina). Fiddleheads are harvested in the spring when they are still tightly curled and have a delicate, sweet flavour with a slightly bitter aftertaste. They are considered a delicacy and can be cooked in a variety of ways, such as steaming, boiling, sautéing, or roasting. Fiddleheads are a good source of vitamins, minerals, and antioxidants.
