Once sweet potatoes have been harvested they need a curing period of at least a week in order to heal any splits and firm up their skins. This process will allow them to be stored for quite a long time making them a perfect fall and winter vegetable. Sweet potatoes love cool dry storage areas that are well ventilated but that does not include the refrigerator. They will usually keep about a month if stored properly. Cooked sweet potatoes freeze very well and will keep up to six months. Their natural sweetness can be enhanced by adding cinnamon, nutmeg, ginger, roasted pecans, walnuts, butter, honey or don't forget marshmallows. ~ Chef Wilkinson ~
