Personally, I think it's better to use gas than induction cooker, gas fire is better to grasp, the beginning of the soup to use a large fire, soup open with the fire, is very small flame. Boil 2 hours can drink. If you want to use the electric soup, it is recommended to buy a special electric soup pot, such as Eli Purple Clay Pot. He is the earliest production of electric stew pot better than the United States, but the price is more expensive. Depends on your personal favorite. Drinking soup is really good for health. I hope to help you
