In a bowl or a large sealable bag, combine your mixture and the pork. Let it marinate for 30 minutes while it comes up to room temperature. While this is going on, preheat your oven to 450 degrees.
Drain most of the liquid and transfer pork to a baking dish and bake until the internal temperature reaches 145 degrees – approximately 35 – 45 minutes. Remove from the oven and let the pork rest for a full 10 minutes before slicing.
