If they are to be dried, they are harvested when it is more fibrous and mature.India is the largest producer and exporter of ginger.Fresh ginger is bulbous, tan or pale beige in colour and is firm. It has a cream or yellow interior which is fibrous, but easy to slice. The skin is very thin and shiny and is quite easy to peel.
