Yesterday while at a grocery store I came upon something I never had seen before.
These were huge in size! Below you will see it is used to make halo-halo which I have tasted, and enjoyed very much!
Ripe jackfruit is naturally sweet, with subtle flavoring. It can be used to make a variety of dishes, including custards, cakes, or mixed with shaved ice as es teler in Indonesia or halo-halo in the Philippines. For making the traditional breakfast dish in southern India, idlis, the fruit is used with rice as an ingredient and jackfruit leaves are used as a wrapping for steaming. Jackfruit dosas can be prepared by grinding jackfruit flesh along with the batter. Ripe jackfruit arils are sometimes seeded, fried, or freeze-dried and sold as jackfruit chips.
The seeds from ripe fruits are edible, and are said to have a milky, sweet taste often compared to Brazil nuts. They may be boiled, baked, or roasted. When roasted, the flavor of the seeds is comparable to chestnuts. Seeds are used as snacks (either by boiling or fire-roasting) or to make desserts. In Java, the seeds are commonly cooked and seasoned with salt as a snack. They are quite commonly used in curry in India in the form of a traditional lentil and vegetable mix curry.
