Last Sat I had my second attempt on Homemade Char Sau using the Buffalo Smart Cooker. During the first attempt few months ago, the taste was ok but the Char Sau looked too MJ (not black enough) since the recipe did not mention putting in dark soy sauce and I followed strictly. But for this second attempt, I put in dark soy sauce and lots of it. And the results look more like Char Sau. Taste wise? I give myself two thumbs up!
