Method

• 1.
  Preheat the oven to 180°C. Line a baking tray with non-stick baking paper.
• 2.
  Prick the unpeeled potatoes all over with a fork, then place them in a large baking dish. Bake for 40 minutes. Remove from oven and leave the potatoes to stand for 15 minutes or until they're cool enough to handle safely.
• 3.
  Cut the potatoes into quarters lengthways and scoop out some of the potato flesh, leaving about 1-1.5cm flesh inside the skin. Place the hollowed out potato quarters, skin-side down, on the prepared baking tray.
• 4.
  Combine the grated cheddar and mozzarella cheeses and seasoning mix in a bowl and scatter over potatoes. Bake for 10 minutes or until cheese is melted and golden.
• 5.
  Serve topped with sour cream.
