Pit beef is kind of a Baltimore thing and there are lots of roadside stands that sell it and it's good stuff. Here's a little interpretation of it today with one of my Newfie Moose roasts. I'm building the case with SWMBO for a meat slicer as this stuff should be paper thin but we work with what have (and celebrate the Ravens win!)
3 lb roast Rubbed with salt, pepper, garlic powder, smoked paprika, a small amount of cayenne and some oregano. On the gas grill at 500 degrees long enough to get a sear, about 3 minutes per side, and then to the oven at 250 wrapped in a double layer of foil until it read 145 then rested. A little bit more well done than I prefer but first attempt.
Pretzel roll (another deviation from the norm) some creamy horseradish sauce and a few onions and in business. Life is good.
