1.Boil sweet potatoes and cook until tender , about 15 minutes. Drain, and immediately immerse in cold water to loosen skins for easier removal. Drain, remove skins, and mash.
2. In a medium bowl, mix together flour, baking powder, salt, and nutmeg. Mix mashed sweet potatoes, eggs, milk and butter in a separate medium bowl. Blend sweet potato mixture into the flour mixture to form a batter.
3. Preheat a lightly greased pan over medium-high heat. Drop batter mixture onto the prepared griddle by heaping tablespoonfuls, and cook until golden brown, turning once with a spatula when the surface begins to bubble.
