Americans would also be surprised how much that hasn't really changed, it just goes on behind the scenes before our meat gets to the grocery. For instance, chicken feet is still a delicacy in China. (I have eaten it, but don't particularly care for it). A lot of the chicken feet Chinese people eat is sent from the US, where it is wasted here. Same with dark meat. From what I have seen, KFC in China is practically nothing more than their dark meat chicken outlet, because we prefer the light meat.
Fixing things like chicken feet is a lost art. I remember getting a cook book on Amish cooking and one of the receipes was for calf’s head soup......first you get a calfs head. Thats where I quit reading.....:O)
