Ginger is used in almost every curry that I make. However, it is also used across the world in different cuisines. It is a tricky thing to peel, especially if you have a central part of the root with lots of other shoots coming off it.
If you use a knife or peeler to peel it you end up wasting a lot, so the easiest and quickest way to do it is by using a tea spoon. It takes off a really thin layer of skin and it's great for getting in-between all the nooks and crannies ! The ginger skin that you remove is perfect for making a quick cup of ginger tea also.
