Method of cooking steak
A Pittsburgh rare steak is one that has been heated to a very high temperature very quickly, so it is charred on the outside but still rare or raw on the inside. The degree of rareness and the amount of charring on the outside may vary according to taste. The term "Pittsburgh rare" is used in some parts of the American Midwest and Eastern Seaboard, but similar methods of sear cooking are known by different terms elsewhere, including Blue Steak, Chicago-style rare and, in Pittsburgh itself[citation needed], black and blue.[1][2]
