Like many home cooks I love to collect all kinds of cooking utensils, appliances, cookware and tableware. I own a strawberry huller, fish poacher, taco frying tongs and artichoke plates. Then after using them once or twice they’re usually banished deep in a drawer or at the back of a kitchen cabinet, where they’re undiscovered for years. But there is one curious looking specialty clay pot, with a steam spout in the middle, that I use regularly for making the most delicious chicken soup. It is a Yunnan (雲南) steam clay pot (汽鍋).
