Method 2: (for taro) peeling can be easy and simple, and it won't make your hands itch! The method is simple:

Prepare a pot of boiling water, wash the skin of taro, remove dirt and impurities, and directly throw it into boiling water for boiling. After the pot is lifted, the skin can be removed effortlessly as long as a knife is gently scratched from top to bottom with a kitchen knife.
