Fiddlehead
Furled fern fronds harvested as a seasonal vegetable.
Fiddleheads, also known as fiddlehead greens, are the furled fronds of young ferns, harvested for use as a vegetable. They are cut early in the season, before the frond has unrolled, and are named for their resemblance to the scroll ornament on a stringed instrument or a bishop's crozier. Fiddleheads have been part of traditional diets in Northern France since the beginning of the Middle Ages, across Asia, and among Native Americans for centuries, and are also consumed in the Russian Far East.

Lore & Background
Fiddleheads are the furled fronds of fledgling ferns, harvested before they unroll into full fronds. They are cut close to the ground early in the season. The name derives from the curled ornamentation on the end of a stringed instrument, such as a fiddle, and they are also called a crozier after the curved staff used by bishops. Not all fern species are safe to eat; bracken contains ptaquiloside and thiaminase, while Diplazium esculentum lacks ptaquiloside and is regularly consumed in parts of East Asia.
Reader's Guide
Fiddleheads have been a traditional food in Northern France since the early Middle Ages, across Asia, and among Native Americans for centuries. In East Asia, bracken fiddleheads are eaten as kogomi in Japan, gosari in Korea, and juécài in China. In Korea, they are used in bibimbap and yukgaejang. In Japan, they are considered sansai (wild vegetables) and used in warabimochi. In North America, ostrich ferns are harvested in northeastern regions, with commercial harvesting in New Brunswick, Quebec, and Maine. The Maliseet, Mi'kmaq, and Penobscot peoples traditionally harvested them. Fiddleheads are low in sodium but rich in potassium. Many ferns contain thiaminase, which can lead to beriberi if consumed in excess. Bracken is considered toxic, and ostrich fern may contain an unidentified toxin. Consumption of raw or undercooked fiddleheads causes acute gastrointestinal symptoms lasting 24 hours to three days. Health authorities recommend boiling for 15 minutes or steaming for 10–12 minutes.
