It's a lot of work to peel off the ginger, but it is worth it. Boil water and added raw sugar untill sugar is solved in the water. Then add peeled ginger after cutting the larger pieces in little ones, and lighty boil for 1hr. Remove the ginger pieces: you can eat them as candy.
Ginger syrop is very tasteful added to Water Kefir.
