Weird question, I know, but my wife asked if I could make siu mai that didn't have bamboo flavoring from the steamer. My steamer is about two years old, I've used it 10-15 times. The bamboo scent it leaves behind isn't obnoxious to me. Others might even like it. But I'm trying to make my main customer happy. That bamboo scent hasn't been on any dim sum I've had at dim sum parlors. Maybe my steamer is still "new"? What do you have to do, boil the thing for a while?
