Daikon

Choose firm daikon with smooth, unwrinkled skin. Peel before using. Grated daikon is used in dipping sauces for noodles and tempura and other fried foods (it is believed to aid in digestion) and is served with certain types of grilled fish. To grate, use any fine-rasp grater or an oroshi. Grated daikon releases a lot of water, which you must squeeze out by hand before serving. Red radishes have a sharper flavor than daikon, but they can be peeled and used if daikon is unavailable.
