Most people love eating potatoes, but no one likes to peel them. Peeling potatoes is such a tedious task that it's often delegated as a punishment (at least in television). The best way to avoid this tedious process is through this special trick: Cut a ring around the potato skin and then boil. When you pull them out, the skins will just glide off. It's so easy, you're probably shocked you never thought of it.
