Double Potato Mash
Preheat the oven to 425 degrees F.
Loosely wrap the sweet potatoes individually in aluminium foil and cook in the oven for 1 1/2 hours or until cooked through. Leave to cool in their foil parcels.
Open the sweet potato parcels carefully over the mashed white potatoes to catch all the juices that have leaked from them. Still holding each sweet potato over the other potatoes, peel the skin away with your fingers and scoop out the flesh into the mash.
Add the oil and mace and beat the potatoes together very well with a wooden spoon adding salt and pepper, to taste. Serve immediately.
