I actually prefer to use yams.. So it’s really mashed yams.. I love the orange color of the yam.. anyway, Place whole yams in a preheated 350 oven. Bake until fork tender (about 45 min) Remove from oven & slice in half lengthwise & scoop the potatoes in a bowl (throw way skins)..add butter & salt & a pinch of cinnamon & sugar & beat with mixer until smooth.
