I think Michal has a prepation that he calls "extra char, extra rare." I'd be interested to know the difference between that preparation and "Pittsburgh Style."
My my have I been busy the past coupla days (wink, wink, nudge, nudge, knowwhatImean, knowwhatImean)...Apologies for the delayed response.
The avoidance of confusing, contradictory and subjective descriptions is of utmost importance in the proper cooking of steaks, as is the proper use of the proper cooking equipment. That is why we take extra care in verifying the exact desire of the guest both in internal degree of doneness and external degree of char, in terms that are more absolute than interpretive. In order to do so, we have to reject the surprisingly subjective, varying and inconsistent terms of "Pittsburgh" and "Black and Blue" and translate them into the more universal, less subject-to-contadictory-definitions of "Extra Rare/Extra Char", at the same time explaining to the guest that XR/XChar is also the only one of these three similar but intrinsically distinct styles that is possible on our cooking equipment with our well-aged beef. It is the extra measure of due diligence that would make a lawyer proud, if lawyers had human feelings.
"PittsburgH" is a style of cooking that, properly, requires the steak to be seared directly on a white-hot flat-top range until burnt (carbonized) on the outside, but still cold-raw on the inside. (Difference between burnt and charred? The controlled charring of beef allows the natural sugars, proteins, juices and seasonings to combine, develop, intensify and caramelize into a heightened, deepened deliciousness. Burnt is, well, just burnt. The reason I prefer our style of aging to dry-aging for today's modern beef and ultra-high cooking temperatures? One, no one really does it correctly any more (sort of like the semi-colon) or is truthful about their aging process; and two, the release and synthesis of sugars, proteins and juices crucial to high-temperature charring is actually retarded by dry-aging beef. When is dry-aging optimal? Ask me in another question and I, blind Tiresias, old man with wrinkled dugs, will perceive the scene and foretell all).
Apocryphally, the term "PittsburgH" derives from the practice of steelworkers of bringing raw meat in their lunch pails and slapping it against the sides of the cauldrons--When we three shall meet again--filled with molten ore.
"Black and Blue" is, properly, a steak cooked in a glowingly red-hot cast iron pan or griddle until somewhat thickly charred with a slight top layer of carbon and a cold-rare (blue-tinged) center. Properly aged beef can never have a "blue" center due to oxygen penetration and other morbid causes. So we can't do "Black and Blue" even though we do have a steak called, in hommage to Louis Armstrong (My only sin is the color of my skin/What did I do to be so Black and so Blue?), The Black and Blue New Yorker, which is a NY Strip with a black-peppercorn crust topped with blue cheese.
Extra Rare/Extra Char is accomplished only on an open flame grill, not possible in the big steakhouse closed broilers--they can only approximate, and our method of achieving the optimal combination of pleasing, intense char with the special succulence and buttery texture of an uncooked center. It is not available on all steaks, depending on thickness and fat content (one way to "cheat" extra char out of a broiler or an improperly aged steak is to dip the steak repeatedly in oil).
By the way, Michal was the biblical David's first wife whose father demanded of David the foreskins of 160 (I think) Philistines as dowry. I may count the metaphorical collection of foreskins from philistine bloggers and others as among my few pleasures, but I am no David. However--Ani l'dodi v-dodi li, baby, and all that--I will certainly tend to any lamb brought my way. She shall not want.
