This is a kind of iced sweets often eaten in the south of the Yangtze River in summer. It is very homely, but it has a very unique charm. The glutinous rice and mung beans are steamed and kept in the refrigerator. When you want to eat, you can scoop some glutinous rice and mung beans, add some cold boiled rice and sugar. Sometimes it’s too hot to eat, just take it as the staple food of the day, which can relieve the symptoms and fill the stomach! I improved a little bit of ordinary home-style cooking, and made this delicious and sweet secret mung bean soup, a must-have for the Consumer Agency.
