There's a way to cook a steak called black and blue. It was invented by steel foundry workers.

Basically you take a thiner steak and slap it on a red hot slab of steel for a few seconds each side.

You get a nice outer char mixed with an almost raw center.

Anyway, red hot steel is not something that most people have access to, but I have a few different types of forge, both solid fuel and gas.
