A young, edible, tightly coiled fern frond that resembles the spiral end of a violin (fiddle). It is also referred to as 'ostrich fern' and 'pohole'. The shoots are in their coiled form for only about 2 weeks before they unfurl into graceful greenery. Fiddlehead ferns are a rich, deep green color and are about 2 inches long and 11⁄2 inches in diameter. They have a flavor akin to an asparagus-green bean-Okra cross and a texture that's appealingly chewy. Fiddleheads can be found throughout the eastern half of the United States.
