The Charleston sweet potato has many unique characteristics when compared to its orange counterparts. Unlike most varieties of sweet potatoes, the Charleston has a dark purple skin and vibrant purple flesh that intensifies when cooked. It is an excellent source of vitamin C and fiber and is the sweet potato variety with the most anthocyanins: the antioxidant found in the purple pigmentation that is known to fight cancer. A staple in Asian cuisine, the Charleston Purple has a drier, denser texture and more balanced sweetness than orange-fleshed sweet potatoes.
The Purple shares many physical characteristics with the russet potato, but in terms of flavor, they are very different. The Purple sweet potato is most commonly used in oriental style cooking. The bright purple skin makes for beautiful presentation and adds vibrant color to any dish. Its soft white flesh is loaded with vitamin C and dietary fiber and is a great source of healthy carbohydrates.
When storing your sweet potato, do not refrigerate as it will form a hard core in the center. Keep in a cool, dry, and well-ventilated container like a bin or basket.
