2-3 sweet potatoes
1 tsp butter
1 Tbsp brown sugar
Wash and dry the sweet potatoes. Wrap well in foil and bake at 350-400° until soft, about 35-45 minutes. (I cook them with other stuff, like a batch of muffins, to save time.) Let cool 10 mins, then peel.
Mash potatoes with a fork, then stir in butter and brown sugar. Serve with an orange slice to squeeze over top.
