Preheat the oven to 175 degrees Celsius.
Dress the Gammon with oil, mix the basting ingredients and add salt and pepper accordingly.
Brush the Gammon with the basting sauce and arrange the apples and Hasselback potatoes in your baking tray.
Bake the Gammon for 40-45 minutes and check to see if the Gammon is cooked through. Lower the heat to 160 degrees Celsius and cook for another 20 minutes. (The perfect cooking time for Gammon is 30 minutes for every 500g).
Serve the Gammon with fresh apple sliced, fresh cherries and rosemary and the crispy baked Hasselback potatoes.
