Preheat oven to 200°C/180°C fan/gas mark 6.
Prick the sweet potatoes all over with a fork.
Place the sweet potatoes directly onto the oven’s wire rack and bake for 45 minutes or until soft. Be sure to place a tray underneath to catch the syrup of the vegetables.
When the sweet potatoes are cooked, remove from the oven and make a slit down the side on each sweet potato.
The flesh should slide easily out of its jacket. Place all the sweet potato flesh in a large bowl or pot, and discard the skins.
Mash the sweet potato with a fork or masher, along with fat and spice of your choice. Season to taste.
Serve immediately as a side dish to a meal.
