Chop an unripe jack fruit and sliced off its skin with an extreme sharp cutting knife. (It is best done under running water or your both hands rubbed with cooking oil before you do the job. Or else the sticky sap from the unripe fruit will be sticky enough to glue your fingers together!!!)
After ripping off the fruit, then cut into cube forms or small pieces with the nuts embedded. With thorough rinsing off the sap, you can heat up your wok. (In between quick chop few slices of garlic, chillies and onions if you wish, add in archovies or prawn paste or dried prawns as your liking to stir the ingredients before adding the young jack fruit.)
Let it cook for some 20 minutes with minimum water and serve while hot.. Yummy .. sweet and tender.
