Disclosure:I am from Kerala so probably a bit biased in favor.

Jackfruit can be used to make jam, dried chips, curries and a bunch of other things that my limited vocabulary restricts me from mentioning. Ofcourse ripe jack fruit is delicious by itself.

To top this, the seed of jackfruit is also used for preparing varios curries. This fruit has a potential that is yet to be tapped to its fullest.
