Pingding casserole, Yingjing casserole, Yixing purple sand casserole, which stew is better?
Pingding casserole, Jing Rong casserole and Yixing purple casserole, I think Yixing purple casserole is better for soup, because the Yixing purple casserole I use is made according to the principle of soup pot, and the air inside is tightly sealed, and the boiled soup is delicious, so I think Yixing purple casserole is better for soup.
