Baked sweet potatoes make a delicious snack all by themselves, or can be pureed to make an ingredient for baking. Bake in 350 F oven. Wash and scrub well. Use a piece of parchment paper big enough to wrap around sweet potato once just like wrapping a hard candy with the ends twisted. Place in oven and bake from 35 to 50 minutes depending on size but until completely tender. Allow to cool and remove spoon and mash. To store for later use, store sweet potatoes in the refrigerator without removing the parchment paper. They make delicious snacks.
