I have no idea how to use it but we made Klepon in indonesian at school ages ago which were really interesting and had palm sugar in them so yea you could google it and find a recipe
But basically Its a boiled rice cake, stuffed with gula jawa (palm sugar), and rolled in grated coconut, and its green..... i think its vegan but i'm not sure
I sort of liked them but i'm a really picky eater so they would probably be quite nice
...oh and the palm sugar in the middle of the klepon did actually taste really good
