Boneless beef brisket, flat cut
Liquid smoke
Bar-b-cue sauce

Sprinkle liquid smoke on beef brisket. Wrap tightly in aluminum foil, making sure it is sealed. Cook in oven at 325 degrees for approximately 3 to 4 hours. Slice thinly against the grain and lay brisket in shallow cooking pan. Cover with bar-b-cue sauce and heat. (The brisket can be cooked ahead of time and kept in refrigerator before slicing. Take it out when needed, slice, cover with bar-b-cue sauce and heat.)
