Powder
If you grind rice, every part of it, eventually it will become a fine powder. You can then use this rice powder as a part to create some other dish. Some kind of cake, perhaps.

Actually, grinding the rice down to a powder is super fun (ふん). It’s so fun you don’t want to stop! AH HAHAHAHA! RICE POWDER! SO FUN!
