I found this recipe for grilled porterhouse steaks with just three ingredients (steak, mixed whole peppercorns, & coarse salt). I'd like to try it, but all I have is T-Bone steaks (four that total about 3 pounds). How should I change the recipe for the type & amount of steak I have? Also, if I use a broiler pan, about how long do you think the steaks will take to cook? Thanks.
