SOUR SOP, or Guanabana

a fruit nearly akin to the Sweet Sop but larger--good examples weighing four or five pounds--and with a thick greenish skin, marked at regular intervals with occasional blunt spines, taking the place of the "pineapple" effect. The cottony white flesh is aromatic in flavor but rather tart. The most pleasing way of service is as a frozen dessert resembling ice cream--the flesh is passed through a colander, beaten well, strained, sweetened to taste and frozen. It is also variously preserved, one of its commercial forms of West Indian preparation consisting of the flesh canned in a thin syrup--being thus pleasing to the taste, but still retaining the objectionable cottony texture.
