Originating in Boretto, a small town in the province of Reggio Emilia, whose name they bear, Borettana onions have been cultivated since the 1400’s and for centuries were sold only by local producers. Prized throughout Italy for their unique flavour, they travelled across Europe and to America with Italian immigrants in the 19th century.
