The jackfruit is a species of tree in the mulberry family (Moraceae), which is native to parts of South and Southeast Asia. It is well suited to tropical lowlands. Its fruit is the largest tree borne fruit in the world, seldom less than about 25 cm (10 in) in diameter. Even a relatively thin tree, around 10 cm (4 in) diameter, can bear large fruit. The fruits can reach 36 kg (80 lbs) in weight and up to 90 cm (36 in) long and 50 cm (20 in) in diameter. The jackfruit is something of an acquired taste, but it is very popular in many parts of the world. The sweet yellow flesh around the seeds is about 3–5 mm thick and has a taste similar to that of pineapple, but milder and less juicy, though some have said its taste is somewhat reminiscent of cantaloupe. The Mexican variety of the Jackfruit tastes of fruit cocktail. Flavours of pineapple, strawberry, and peach can be discerned. This variety bears smaller fruits than the S.E.Asia type and the trees are likewise smaller.  The term Jackfruit derives from Portuguese jaca, which was imported from Malayalam chakka.

The jackfruit (not to be confused with the Durian fruit) is native to India, Bangladesh, Nepal and Sri Lanka. It is also possibly native to the Malay Peninsula, although it may have been introduced there by humans. It is commercially grown and sold in South, Southeast Asia and northern Australia. It is also grown in parts of Hawaii, Brazil, Suriname, Madagascar, and in islands of the West Indies such as Jamaica...
