Why are they called “Boston Butts”

In pre-revolutionary New England and into the Revolutionary War, some pork cuts (not those highly valued, or "high on the hog," like loin and ham) were packed into casks or barrels (also known as "butts") for storage and shipment. The way the hog shoulder was cut in the Boston area became known in other regions as "Boston Butt." This name stuck and today, Boston butt is called that almost everywhere in the US…except in Boston!
