The casaba is a large, smooth-fleshed winter melon, the wrinkled, golden-rinded fruit of the trailing gourd vine Cucumis melo (Inodorus group). It is one of the mildest of the sweet melons — pale, juicy, faintly cucumber-fresh and almost odourless — eaten chilled in wedges, balled into fruit salad, and prized as a long-keeping melon that holds for weeks after harvest.
