to cook, canned jackfruit is available in most asian stores in the US (thai, laotian, cambodian). I found it uninspiring, alas.
there are a few kinds of jackfruit. he's got the more solid kind- where i live they tend to be the softer, more fragrant kind, but also the kind you don't dare cut inside your home, because your kitchen/knife/board will be covered with a horribly sticky latex and you'll start thinking you're going to die like a
mouse on a sticky trap.
I DO really like these videos because they show what you can do with what you have available in volume, locally- you can make a darn good curry with those same ingredients with chayote, or zucchini, or green bananas, or green papayas, or broccoli stems, or whatever you have a glut of. You're not going to get exactly the same texture, but it shows the ingenuity of using what you've got-- very
permie.
