Break the taro stalk, tear it in half, marinate it with a little salt, and then pour in white vinegar. Grasp it with both hands, and be sure not to use too much force. After adding salt, you don't need to add salt to the fried taro and lotus root. Then wash it clean, rinse it several times, the more the better, and grab the water hard, so that the fried taro stalks will not itch to the throat.
