Dried ginger is nothing but fresh ginger which undergoes a drying process before being used. The fresh rhizomes are soaked in water overnight after which the outer peel is carefully removed using a knife or a peeler. They are washed again and then sun dried on mats or barbecues for around a week. It's sweet, peppery and a bit floral, with a hint of citrus. There are lots of spices in gingerbread, but ground ginger plays the headlining role.
