Preheat oven to 425 degrees F. Line baking sheet with foil & spray with nonstick cooking spray. Wash & dry potatoes. Make a series of slices along the top of each potato, stopping 1/2 inch from the bottom. Stir all other ingredients together in a mixing bowl into a rich glaze, then brush have the mixture generously over the sliced potatoes. Bake in oven for 40 minutes. Brush on the remaining glaze mixture and bake another 10-20 minutes (or until the center slices are very tender). Serve & enjoy!
