Jackfruit (left), pineapple (top), and banana (right). Jackfruit is a difficult fruit to describe. It tastes sweet like honey, with perhaps a hint of banana. It has the same freshness as lychee, but it's definitely harder than it. It has veins/fibers similar to but longer and stronger than the ones in pomelo, but the texture resemble nevertheless made us think we could plausibly say it was like dried pomelo.
Anyway, you see how hard it is to describe?
