Wash and peel the ginger root. You can use a knife or spoon to remove the skin.
Chop the ginger root into rough chunks, or grate it if you prefer.
Blend the ginger root with 1 cup of water until it is thick and pasty. Then, mix it with mint leaves and boiled water.
Strain the ginger juice using cheesecloth or a fine-mesh strainer. Discard the remaining pulp.
