Preheat the oven to 350 degrees. Rub kosher salt all over the pork roast. Warm the oil in a skillet over medium heat. Brown the roast on all sides and then set aside. Mix the pepper into the apple butter and then generously rub and cover the roast on all sides with the mixture. Place in a baking dish and roast until internal temperature is 145 degrees.
Cooking time was 70-80 minutes, however I did allow the uncooked roast to rest at room temperature for about an hour prior to cooking it. If you are cooking a cold roast straight from the fridge, it will take a little while longer. Enjoy!
