Stir in enough of the simmering stock or broth to just cover the farro. The stock should bubble slowly. Cook, stirring often, until it is just about absorbed. Add another ladleful or two of the stock and continue to cook in this fashion, not too fast and not too slowly, adding more stock when the farro is almost dry and stirring often, until mixture is creamy and farro is tender, about 25 minutes. Taste, adjust salt, and add pepper.
