The chicken below was brined in Keller's herb-lemon brine (brining appears to be one of those things restaurants do often, but home cooks neglect) for 8 hours, then dripped in flour, buttermilk and then flour again before being dropped into canola oil at 325 degrees. I had a mild temperature disaster when I realized my pan was too small, and had to transfer frying chicken into a larger pot (it's like transporting a living organ) but a quick adjustment of heat saved the day. The resulting chicken was crunchy and extremely flavorful - just a delight.
Still, I think I need an instant read thermometer for frying, candy, etc. Flying by the seat of my pants leaves too much to chance.
EDIT: As delightful as it was, I'm reminded by looking at the picture that the fleur de sel I added on top was overkill, given my generous salting of the batter. As I've heard before, if you can taste salt rather than the enhanced flavor of the food, you've gone too far.
