Korea cool rice cooker to make rice 枮 Why?
The principle of non-stick cookware is the same, brush a layer of coating on the inside of the pan, so that the rice does not stick to it, the coating falls off, it will be stained, and this coating will also be carcinogenic, if the temperature is too high (such as too little water when cooking) the coating will fall off, when brushing the pan is too hard will also fall off, flashy things.
