..this former president's preparation preference was starkly different than most. He'd impress (or sometimes worry) guests by cooking meat right atop coal embers that smoldered on the White House lawn. It's an unusual, but still practiced cooking style called dirty steak, which yields surprisingly spectacular results.
While the method requires some skilled grilling to perfect, when done well, the meat turns out delicious. The blackened external char is not only edible, but tasty, and seals in a beautifully juicy interior that's often on the rarer side. With such an abundance of surface area contact, the charcoal selection is important, but it also imparts a delectable flavor.
