As I recall the fifties, the height of in ness was to build or have built a brick bar b q. The structure was about thirty 6 inches high with a mortared in iron grill. The grill was over a fire box that actually had a chimney.
This is the classic design but the grill is missing.
That’s grilling, not BBQing. BBQ is slowly cooked by indirect heat and smoke and often takes hours, depending on the cut of meat.
