Jean's Preserved Root Ginger

This is my mother's recipe, she always used to freeze her root ginger and then she came up with this idea. As root ginger is called for in so many recipes these days its just so quick and easy to grab straight away out of the fridge. This is brilliant because you can either prepare as little or as much ginger as you wish, its best to make a lot when the good quality ginger is in season!! You only have to make this once a year as it keeps indefinately. I will value your comments with this one
