Jackfruit (both raw & ripe pods) is a key ingredient in the Udupi Cuisine. Jackfruit seeds have an excellent nutty taste and are used extensively in special preparations like Kootu, etc. Jackfruit tree leaves are also used to impart that distinctive flavor to the food. Most food requiring steaming like Idlys, Puttu are wrapped in Jackfruit leaves (which are themselves too fibrous to be consumed).
When I was in Madikeri during early 90s, my mom used to prepare Giguje Palya, Giguje is a fruit from the Jackfruit family and is known as Breadfruit in the tropical countries, where it is extensively grown as a staple food. You prepare it similar to Aloo and has one of the best textures and flavors.
My father extracting the pods from the fruit (which is a skilled effort on its own). I got a big jackfruit on my way back from Madikeri near Hunsur (about 50 kms from Mysore)
