iron

Farro is an old Italian word for Iron and as such can ONLY mean emmer because emmer is the only grain in the world whose limiting factor is iron and will provide 100% of the bodies needs in one cup a day. Farro from italy most often isn't even emmer any more but is spelt. The Italians think the americans can't tell the difference (and they are right - most everybody but I cannot) tell emmer from spelt from barley from wheat from einkorn, especially pearled.
