Sweetie

Sweetie / Oroblanco

Known in Japan as "Sweetie" and elsewhere as Oroblanco, this white grapefruit-pomelo cross was hybridized by researchers at the University of California. Thanks to its Pomelo parentage, the sweet flesh is surrounded by a tough green or gold rind and a half-inch of doughy, dead-white pith. Just as UC intended, the flavor is sweeter and less tangy than a grapefruit, although the membranes between the flesh sections are just as bitter. I found that the flavor lingered for an oddly long time, growing unpleasantly metallic.
