Coca cola pork loin (I'm sure caffeine free would work!)

Ingredients:3-5 lb Pork Loin Roast1 Tbsp Smoked Paprika1 Tbsp Ground Marjoram1 Tbsp Seasoning Salt1 tsp Cumin1 tsp Granulated Garlic1 tsp Cracked Black Pepper1 Tbsp olive oil1 liter Coke1 Cup Brown Sugar1 Cup Cornstarch1 Cup WaterMethod:Combine the dry seasonings and rub over the pork loin. In a large roasting pan or cast iron skillet heat the oil. Sear all sided of the loin until crisp. Place the seared loin in a deep pan and cover with a lid or plastic wrap followed by aluminum foil. Place in a 350 deg oven for 1-1 ½ hours until the loin is tender. Remove the loin and allow it to rest for 15 minutes before slicing. Bring the remaining juices to a boil over the stove. Make slurry with cornstarch and water and thicken the sauce. Adjust the seasoning of the sauce with Salt and pepper and Brown sugar if needed.(Note: This recipe is from the Studio 5 show. The instruction about plastic wrap and then foil on the meat and then putting it in the oven sounds odd. Maybe they meant just foil.)
