Once the grill or smoker is up to 225°F and producing smoke, oil the grates and place the oiled and salted raw whole potatoes into the smoker, or on the cool side of the grill. Close the door or lid.
Smoke for about 2 hours and rotate the positions of the potatoes as neccessary for even cooking.
After 2 hours check for doneness by piercing with a fork to see if the times slide in and out easily. Or, use an instant thermometer and once the smoked baked potatoes reach 205°F internally remove them from the smoker or grill.
Cool the potato slightly and cut in half.
Top with butter, shredded cheese, sour cream and chives.
4 tablespoon Butter, 1 Cup Shredded Cheddar Cheese, ½ Cup Sour Cream, Chives
