This is what's inside? Actually I believe it's quite a lot messier than this when it's first opened, but this is Jack Fruit, prepared ready to eat. I'm still waiting for this one to be picked, so I can see what it's like inside. Meanwhile, I was hoping my helper would produce some soon so that I could take a photo and sure enough, she did! Thanks Naomi. Not everyone likes it, but I enjoy it. It's also really good dried! Crunchy! Tasty! And good for you as well!
Thanks to the two people who attempted identification. One knew what it was, but then she has lived in Cambodia a lot longer than I have, so it's probably to be expected. The other thought it might have been "that smelly fruit", by which I think she means Durian. No, that won't find its way into my house, although one day I must take a photo of the stalls selling it that I pass on my way home from school.
