If you want to serve the fondue in the pumpkin shell, heat the oven to 180C/160C/gas 4. Bake it for 1 hr 30 mins until softened but not collapsing. Alternatively, use a serving bowl (we’ve used a bowl from Morrisons Nutmeg range). Tip the pumpkin flesh into a casserole dish with the garlic and cream, bring to a simmer and cook with the lid on until tender, about 10 mins. Take off the heat and mash thoroughly, or use a hand blender if your pumpkin is quite fibrous.
