As barbecues spread across the Americas, there became some interesting debates between the purist and pioneering pitmasters.

In North Carolina, the purists insist barbecue should be pork-based. Their argument is based on the fact that original BBQ masters of the southern colonies farmed pig over cow.

This is where the low and slow method of barbecue was developed. smoking the pork for longer periods to give it that beautiful tender finish. By the time barbecue hit Texas, a new breed of pitmaster was born. Texas had far more room for animals to roam and therefore cattle were bred and slaughtered.

These pioneers took the original low and slow concepts of the North Carolina chefs and swapped out the pork for beef.

The Mississippi River provided Memphis with an abundance of goods, including molasses.

It was here that the traditional barbecue sauce was created, marking another step in barbecue history.
