Preheat oven to 350F. Cut slits on the potatoes, do not cut through. Mix all ingredients in the Oil Mixture together. Place the potatoes in a roasting pan and brush with the Oil Mixture. Make sure to brush inside the slits of the potatoes. Save some for basting. Roast the potato for 1 hour, basting the oil mixture at 30 minute interval using the remaining Oil Mixture. Serve immediately after roasting.
