Pre-heat the oven to 425 degrees. Remove pork from marinade and wipe of some of the excess. Place the pork roast on a grill rack with the fat size up and roast for 20 minutes. Reduce heat to 325 degrees and cook for another 1.5 to 2 hours until tender. The roast will develop a “bark” on the outside as it cooks. Remove from oven and let sit for 15 minutes. Slice into 1″ slices and serve immediately. (yes, I forgot to take a photo of the entire roast before we started eating!)
