Two things: I've had twice cooked pork at Asia Cafe at least 6-7 times (just had it an hour ago---was there for vann's review meal too) and I've never had a smoky flavor to the pork. Ever. This meat has a tinge of skin left on it as well. at least every time i've had it it has. It is not store bought bacon, or never has been in my experience. Maybe you caught an off night. It is the same meat used in the cooked pork with special garlic sauce, an amazing dish, served cold, the flavor of that pork is pure and definitely not bacon. they blanch a chunk of unsliced belly, then slice it before the second cooking, thus twice cooked. 2) Indeed bacon, or smoked belly is used in Chinese cooking. I've seen it for sale in Austin, and eaten it in many restaurants (not in Austin). It is common in Hunan cooking and that has drifted into Sichuan as well. Sichuan Cuisine in Houston and Grand Sichuan in NYC both serve a smoked belly dish with leeks and it is highly recommended. The smoky meat and the sweetish leeks make a wonderful combination. Fuschia Dunlop has a recipe for something like this in her upcoming cookbook which is devoted to Hunan cuisine (got a copy from AmazonUK where it's been out since summer and worth the effort). She even uses regular bacon in the recipe since it's easier to get than Chinese bacon.
