Article in English: Take a section of ginger root and peel away the outer layer with a vegetable peeler. Next, use a small knife to cut away a 1 inch (2.5 cm) cube of fresh ginger. You’re only making 1 cup of tea with this recipe, so you don’t need to include a lot of the actual root. You can find fresh ginger root at most grocery stores.
