Jackfruit has a great, rich taste; I like it, although I don't go much for sweet foods generally (I make an exception now and then, for some). The sticky stuff between the edible parts is a bit of a turnoff, though. Not easy to get it off your hands, once on. Also, the fruit has a strong smell, but not a bad one, IMO.
You cannot eat a lot of it, since it is rather dense, though soft.
It's also one of those wonder plants, like neem, banana and coconut, with many uses.
The easiest way to get them is frozen at an Asian super market. It's already taken out of it's shell and put in an air seal bag then in a plastic box. Some Asian super market have the whole fruit frozen. There are specialized places that import just exotic fruits we have one here in Alhambra near Pasadena iirc.
My parent just bought a jackfruit awhile ago from the specialty fruit importer store. We had to wait for a few days for it to ripe before eating.
Wander around your local Chinatown stores. They should have both Jackfruit and Durian. And if you're really lucky, mangosteen. I'm starting to see Dragonfruit in regular groceries now, so hopefully some of the other fruit should make it there in a few years too.
Jackfruit is another one of my favorites in the tropical fruit world.
