Mango-ginger pickle

This picture is sitting in my draft for more than two years, almost forgotten until I saw some fresh mango ginger in my grocery store. This pickle is excellent and store well in fridge for up to 3 months.
An under exploited spice: Mango-ginger is botanically known as curcuma amada. The rhizome believes to be originated from West Bengal as Am-haldi but widely known in South India. The rhizome is pale yellow inside and has an unripe mango aroma when broken.
It has many medicinal and rich culinary use. The root is prepared as pickle, preserve, candy, and dried to use later in curry.
The root is an excellent medicinal use for: laxative, cure indigestion. The pulp of mango ginger is applied over sprains and bruises to rapid healing. But I never tried any remedies I make only pickle.
