Do not thaw out the frozen glutinous rice balls. Instead, place them frozen directly into the boiling water or soup broth. When you place them in the boiling water, stir them so they do not stick together. You will notice that the soup will stop boiling at first because the cool glutinous rice balls dropped the temperature. Once the soup broth comes up to a rolling bubble, you will add a little cool water to the soup pot. Allow the soup to come to a rolling boil again. Repeat the process a total of 3 times or until the glutinous rice ball dumplings float to the top of the pot. Then, cook at least one minute longer.
