What is black and blue steak?

Black and blue steak, also known as Pittsburgh-style or Chicago-style steak, is a steak that is cooked very quickly at a high temperature. This results in a charred or blackened exterior and an almost raw, or blue, center. The steak is typically seared on a hot grill or in a cast-iron skillet, and then finished in the oven to ensure that the center is cooked through to the diner's desired degree of doneness.

Black and blue steaks are often favored by steak enthusiasts who appreciate the contrast between the caramelized, crusty outer layer and the juicy, tender interior of the meat. However, it is important to note that the consumption of rare or undercooked meat can carry a risk of foodborne illness, and diners should only eat black and blue steak if it has been cooked and handled properly.
