n Viet Nam, there are two kinds of custard apple: firm and soft. Both varieties can have various shapes, for example they can be round or oval. When a custard apples is ripe, it is easy to peel. The peel is thick, green, and covered with white or green pollen. The pulp is white or light yellow and contains many black seeds.  In the south, custard apples call mang cau, ripen in July, but not all at the same time. Firm custard apples are densely grown in the south, mainly in Ninh Thuan and Ba Ria - Vung Tau provinces. Xiem custard apples are oval or heart shaped. Their peel is green with thorns, which turn black when the fruit is ripe. The fruits are generally big and can reach 1.5 kg. The pulp is white, hard, and a bit sour. Custard apple trees deliver fruit after three or four years of growth. A tree produces on average from 50 to 100 fruits per year. The fruits ripen on the tree and then cracks, especially during the rainy season.

Hidden among dense foliage, big as a fist and brownish-violet in colour, is the mangosteen. When eating a mangosteen, use a knife to cut around the fruit and to remove half of the shell.    The inside of the mangosteen is arranged in white, soft sections, and is freshly scented. There are three varieties of mangosteens: the first variety is a little acidic, the second is as sweet as candy, with big segments and a thin shell, and the last variety, called doi mangosteen, has crisp segments. The mangosteen season ordinarily lasts from May to August.

Sapodilla was imported to Viet Nam a long time ago. In the last 20 years, sapodilla has been widely planted in the north, where it grew for the first time in Xuan Dinh, Bac Tu Liem District, Ha Noi.  Sapodilla fruit is shaped like an egg and weighs from 10 to 200 grams. Its peel is brown with tiny cracks near the stalk. The pulp, which is brown and yellow, is very juicy and smells very sweet. When it is not ripe, it is not edible because it contains a lot of sticky resin. There are two popular species of sapodilla grown in Viet Nam: orange pulp and white-yellow pulp sapodilla. The orange pulp sapodilla is planted in the north on the highlands. The pulp of the white-yellow sapodilla is light yellow or yellow and the peel is green or yellow. The peel is thin; the pulp is soft and has taste of peach, banana, and apple.   Sapodilla flower consecutively bloom in bunches so that it has fruits to offer throughout the year.
