I stopped at a local BBQ restaurant and ordered a brisket sandwich. I was asked if I wanted it sliced or chopped. After ordering I was talking to the cook and asked if there was a difference between the two types of brisket sandwiches. He said the chopped comes from the point and the sliced comes from the flat. Is that common knowledge? I assumed that the two types of sandwiches came from to different briskets smoked to different temperatures.
