Either way you prefer! I personally like to bake my sweet potatoes, because it is less work than peeling and boiling the sweet potatoes. Just wrap the sweet potatoes in foil and bake them at 400°F for about 45 to 60 minutes, until they are soft and baked through. Let them cool until you are able to touch them without burning yourself. Then peel off the skins, add them to the bowl and continue on with the recipe.
