Using a sharp knife, make crosswise cuts in each potato, about 1/8-inch apart, stopping about 1/4 inch from the bottom. Add a Dromona butter slice into each of the cuts and season with salt and pepper.

Place the potatoes onto a baking sheet and into the oven. Bake until the outsides are browned and crisp – approx 1 hour. Add the cheese slices into the potato cuts and bake until melted – approx 5 minutes.

Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes.

Serve potatoes immediately, topped with sour cream, bacon and chives.
