Production area: Castiglione del Lago The black chickpea is a variety of chickpea. After harvesting, the black chickpeas are selected and placed in the freezer for a few days before being marketed, to eliminate insects that may develop during storage. What distinguishes the black chickpea from the white one, besides the color, is also the skin, which is thicker, giving the legume more consistency in taste. New Organic Harvest.
