These potatoes can be steamed to preserve more of the flavor and vitamins (or boiled if you wish), until tender. (To steam them, you can place them in a single layer on a rack placed over a large shallow pan of water with a large pot lid to cover. Replenish water in pan if it boils off before they are tender.)
Place the tender potatoes in a large bowl and mash by hand with a masher or fork. Then, using a beater, whip in butter, brown sugar, cinnamon, nutmeg, maple syrup, and enough cream to achieve your desired consistency. Season, to taste, with salt and pepper.
