History of Sweet Potatoes

Sweet potatoes are as American as apple pie! Native Americans were growing sweet potatoes when Columbus came in 1492, and by the 16th century, sweet potatoes were being cultivated in the southern states, where they became a staple in the traditional cuisine. With their delicious sweetness and mild flavor, sweet potatoes take to a variety of ethnic seasonings, making them a go-to ingredient no matter what the season.

From Southern to Thai, Caribbean to BBQ, sweet potatoes are used in cuisines all over the world as a satisfying and versatile vegetable with a well-earned reputation for being nutritious.
