I peel and slice sweet potatoes and layer them in a deep-type casserole dish. I alternate lightly drizzling melted butter and lightly drizzling pancake syrup on the layers, along with sparingly salting every couple of layers. Cinnamon and chopped nuts can also be used on every few layers. Bake at 350. To speed up the baking process, I microwave about 10 minutes before placing in the oven.
