Yep,there reasons/needs to cook less when dollars are at stake.
Across Fl,butts would be cooked to about 170*-175* at all the chain restaurants.There would be less cooking time,less shrinkage,more weight on the serving plate.
Until Smokey Bones came around,you got thick sliced pork roast,usually fatty.
Beef was round,cooked about 160* and thin sliced on a commercial slicer.
BBQ chicken was normal,and ribs were often cooked in steamers and finished on a grill.
Fried catfish and a salad bar were the other items.
Typically a full liquor bar.
Breakfast was usually a standard.
We have a great volume of bbq places,but the quality is pretty sparse,because the dollar dictates.
Several states across the South would undercook and chop with two cleavers,for the same reasons.
Others might cook whole hogs and chop everything but the squeal.
Yep,for "good pulled pork",like Smokin' says'" ITS DONE WHEN ITS DONE",but it sure is worth it.
