Of course, it is perfect for enjoying authentic dim sum at home, and I think it is also sufficient for professional use. Boil water in a pot, place this steamer on the pot, and steam. It is an indispensable tool for Chinese dim sum such as pork buns, soup dumplings, and shumai. It also seems to be useful for steamed vegetables, leftover cold rice, and side dishes. When using, be careful not to burn the pot. Add water frequently. Why not use a steamer to cook and improve your physical condition during the rainy season when the cold is a concern!
