I have always heard you can cook with Jack Fruit and was a good replacement for meat.
Yes, there are the fake meat products made from jackfruit. The ones I have tried are pretty tasty.
I just wondered how you would make those when there is so little to work with, but after you posted, I looked it up, and actually those many, many seeds are edible, so maybe they blend it all up, seeds and all, with seasonings, spread it all out, bake it and cut it up.
I'm not gonna try it. It was a big annoyance to try to work with jackfruit. With spaghetti squash, you bake it whole, let it cool, cut it open, scoop out the seeds and you have all the lovely sweet baked flesh to use for soup, pasta sauce or whatever you want to make.
