China traditional old-fashioned casserole recommended Zhihu.

In the electric frying pan, there will be a metal heater at the bottom. Although it is made of copper or other materials, it is not very good after all. In contrast, it may be more convenient. But this dose is not easy to control because water does not pass through the heater. Because the dose prescribed by the doctor is not always the same, sometimes you may have to drink a big bowl, and sometimes you have to prevent the medicine from boiling. So, if conditions permit, let's use the most primitive pot. It is the simplest and most effective to enlarge the fire and cook it slowly. But it should be noted that you can't paste the pot, and Chinese medicine is not allowed to paste. Once burnt, it must be thrown away.

I hope this helps.
