Dried ginger is nothing but fresh ginger, which has undergone a drying process. The fresh rhizomes are soaked in water overnight after which the outer peel is carefully removed using a knife or a peeler. They have washed again and then sun-dried on mats or barbecues for around a week. During this period, they are turned periodically. The end result is a pale white dried ginger. Many times, dried ginger is bleached with calcium carbonate to get a whitish coating, but this is unnecessary and better avoided.
When this dried ginger is powdered in a mixer, we get dried ginger powder. It is a fine off-whitish powder, which has a strong aroma and slightly pungent flavor.
