To prepare a vanilla and black pepper pork loin recipe, combine the following ingredients: 12 cup vanilla bean paste, 2 tablespoons kosher salt, 1 teaspoon vanilla extract, and 2 teaspoons freshly ground pepper. Cover and refrigerate overnight. Preheat the oven to 375?F (190?C) and grease 2 large roasting pans with vegetable oil. Add the pork to the pan and cook until browned on all sides, about 1 hour. Remove from the heat and allow to rest for 10 minutes before carving. Serve with vanilla ice cream and sour cream.
