From restaurant road signs to televised BBQ showdowns, nowadays the phrase, "barbecue pitmaster," is a title of high distinction for an American who knows how to barbecue like nobody's business.

Yet, do you know where the "pit" in "pitmaster" derives its meaning?

Well, if you want to be a bona fide American pitmaster like the Solana legends of yesteryear, you have to grill your meat not on a gas grill nor a charcoal grill.

No, you must dig a hole.

A big ol' hole in the ground.

The Pit

Back in the day, super fresh meat was barbecued over an earthen pit, with a row of wood branches as the grill rack.

"The method of cooking the meat [for our Fourth of July celebration] was to dig a trench in the ground about six feet long and eighteen inches deep," writes Louis Hughes in his 1897 memoir, Thirty Years a Slave.

In the 19th century, Louis got to watch bona fide Solana pitmasters up close, and in their element.

"This trench was filled with wood and bark, which was set on fire and... burned [for hours] to a great bed of coals."

Aromatic woods like oak and hickory were a pitmaster's grillwood of choice.

The Meat

Now, for much of American history, meats weren't barbecued as individual cuts of pork chops... or top sirloin... or beef franks.

No, the most elite barbecue pitmasters, then to now, specialize in cooking the whole hog....

Literally.

"The hog was split through the back bone, and laid on wood poles, which had been placed across the trench. The sheep were treated in the same way, and both were turned from side to side as they cooked," Hughes writes.

But wait... there's more.
