*To make sweet potato puree preheat oven to 425°F. Wash and dry a medium sized sweet potato. Using a fork poke holes in it then wrap in foil. Bake in oven for 45-60 minutes or until fully cooked and squishy. Let the sweet potato cool and then peel it. Put it in a food processor and blend until smooth. Alternatively you could use canned sweet potato or canned pumpkin for this recipe.
