Peel the skin of the galangal with a vegetable peeler, then use a rolling pin or something heavy to bruise the galangal and lemongrass and add both to a casserole. Drain the liquid from tins of jackfruit and tip the flesh into the casserole along with the spice paste, Indonesian bay leaves, kaffir lime leaves, black tea bags, palm sugar and coconut milk. Fill the empty coconut tin with water and pour it into the casserole along with 2 tsp salt. Make sure that everything is covered with liquid, otherwise top it up with a bit more water. Bring it to a boil, then reduce to a simmer, cover with a lid and cook for an hour. Now remove the lid and continue cooking until the jackfruit has absorbed all of the liquid (1 - 2 hours), stirring every 30 minutes so that it doesn’t burn. Remove the galangal, lemongrass, bay leaves, lime leaves and tea bags and serve the stew on the banana leaves alongside some steamed rice and the Tahu Tempe Bacem and Sambal below.
