There is a kind of rice with small white grains sold in the supermarket, which seems to be called sago. When cooked, it becomes a small transparent white ball, which is smooth and waxy. If it is cooked for a long time, it will melt and can be used to make porridge. Get shiny, get sticky. But if the time is too long, it will easily burn the pot, so stir frequently. I got through it and it felt pretty good, you can try it.
