Roasted Chestnuts

Another thing that's good to have on a cold winter's night is roasted chestnuts. There were a few street vendor around the area we were staying at in HK. Most of them have a big wok and cook the chestnut with coal chips (???) until they are cooked just perfectly. How could you tell they're cooked right? When it peels easily without anything peel sticks to it. The one shown in the picture was actually taken from Macau, I guess it's a little more "high-tech" method than turning by hand. For $20HK a pound, I can't think of a better snack. (They're nice hand warmer too!)
