Krupuk is one of Indonesian snack. Some of them made out of flour and when you bite it, it will make a crackling sound. Another variant of krupuk made of fish, shrimps, cow skins, or melinjo nuts. It’s easy to get krupuk in Indonesia. You can eat it with main dish such as soto and nasi uduk or just as a snack. My favourite is krupuk emping made of melinjo nut.
