Nutrition fun facts: Sweet potatoes are nutrient powerhouses; serving up some of the highest levels of beta-carotene and vitamin A. The deep pigmentation in sweet potato flesh lends them their nutrient punch, and aid with inflammatory diseases, diseases of the gut, and can even help regulate blood sugar. Purple fleshed sweet potatoes pack in extra inflammation fighting nutrients.
Storage tips: Store sweet potatoes in a cool dry place out of direct sunlight, ideally a cool garage or basement, where the temperature stays around 55 degrees. Store in a box with air holes, paper or cloth bag. Check regularly for sprouting and soft spots. Sweet potatoes will sprout if conditions are too warm and if they are in direct sunlight. When properly stored, sweet potatoes can be stored for upwards of a year. Do not wash sweet potatoes until immediately prior to cooking, as moisture can cause spoilage.
Preparation tips: Sweet potato casseroles are a great holiday tradition, but they only scratch the surface of what sweet potatoes can be used for. They are great roasted whole, sliced into strips and roasted into fries, or cubed and added to a stir-fry. The smaller, and thinner, you cut a sweet potato the faster it will cook. Sweet potatoes are great in soups and stew, or mashed with caramelized onions and ginger. The possibilities are really endless!
