Comment on Chick-fil-A Copycat Chicken Sandwiches by Joel.
I have been making these sandwiches myself for a while now, and the definite secret to these is brining the chicken. Good BBQ places brine their meat all the time, but they just use salt water. The chicken breasts brined in kosher dill pickle juice for at least 12 hours are amazingly exact to the Chik-Fil-A taste, and if you do it at home you can make it organically, if you like. For me, I do a simple dip in an egg wash, then a dip in flour, then egg wash, then flour again. If you can get hold of unrefined peanut oil, fry them in that for that extra southern flavor.
