3 large sweet potatoes
Preheat oven to 425˚F. Line baking sheet with foil.
Wash skins of sweet potatoes under water and dry immediately with paper towel. Using a fork, pierce holes throughout the potatoes.
Place potatoes on the foil-lined baking sheet and bake for 45 - 60 minutes, or until soft inside. When cool enough to handle, peel the potatoes (skin should remove easily) and puree in a food processor, blender, or with a hand mixer. Add boiling water as needed.
