The porcelain grater teeth of Helen's Asian Kitchen Porcelain Ginger Grater are specially designed to extract the delicious spicy pulp from fresh ginger while avoiding the tough, stringy fibers commonly associated with grated ginger. Simply rub peeled ginger in a circular motion over the rows of teeth. The specially-designed bamboo brush helps dislodge and clean any particles of ginger left in the grater's teeth. Can also be used to grate daikon radish, garlic, nutmeg and citrus. Dishwasher safe.
