For those who have never eaten a custard apple, this is a delightful exotic fruit with quite a few important nutrients, a unique taste, and various impressive health benefits.
What is a Custard Apple?
A custard apple is a tropical fruit that is native to Central America and parts of South America, scientifically known as Annona reticulata. Closely related to the soursop, sugar apple, and various citrus fruits, this unique fruit grows on a shrub of the same name and may be called sharifa or sitaphal (India) or bullock’s heart, depending on where in the world you happen to be. The fruit grows from different ovaries that coalesce into one fruit, which is slightly larger than a sugar apple and has a rough exterior. It is vaguely heart-shaped and has a variety of cultivars, meaning that it can be a number of different colors, including maroon, green, brown or yellow. 
The fruit of the custard apple is soft and mealy and is best eaten with a spoon, after removing the numerous black seeds. The consistency of the fruit is what gives it the name “custard”, and it has a tangy and sweet flavor. This fruit has been popular in tropical areas of the world for centuries but has only recently been spread to much of the western world.
