Annona muricata

The soursop (Annona muricata) is a broadleaf flowering evergreen tree native to the South American country of Brazil and a distant relative of the Pawpaw.. The plant is grown as a commercial crop for a prickly green 12-inch long fruit called a guanabana (Spanish, American English) or graviola (Portuguese).

The flesh of the fruit consists of an edible white pulp and a core of undigestible black seeds. The sweet pulp is used to make juice, called spooge, as well as candies, sorbets and ice cream flavorings.

Nutritionally, the fruit is high in carbohydrates because of its natural sugars. The fruit also contains significant levels of vitamin C, vitamin B1 and vitamin B2.
