The mulberry is the soft, elongated aggregate fruit of the mulberry tree, genus Morus, ripening through white and red to a deep purple-black depending on the species and stage. Each fruit is a tight cluster of tiny juicy capsules strung along a slender stalk, eating with a honeyed, grape-like sweetness and a mild tartness that floods the mouth with dark, staining juice. Despite looking almost exactly like a blackberry, it grows not on a bramble but high on a deciduous tree, and has fed people and silkworms across Asia and the temperate world for millennia.
