I had never heard of this place until today and I grew up in BLO, and what is funny to me is that I used to make them like this when I had kids in the house... they loved them like that. All I did was cut the tip off and fry them in peanut oil, then shake them in a sauce that was pretty damn good, I still use that sauce recipe. Not sure where to even find the flats and bats attached anymore.
