Button meat is usually steamed for about 30 minutes after the water is boiled, or up to 15-20 minutes if you use a pressure cooker to steam it. The steamed pork with preserved vegetables should not be steamed for too long, otherwise the fat meat will be vaporized.

Buttoned meat must choose five-flower meat, a layer of fat layer of lean is easy to steam rotten. If you use half-fat half-lean pork, the lean part is too thick is very difficult to steam rotten, and after frying is very dry and faggy, so it's not good.
