TERRA Real Vegetable Chips Crinkle Cut Sweet Potato, Sea Salt, 1.2 Ounce (Pack of 12). Made with Sweet Potatoes. Sweet Potato: A root vegetable often called a yam is not really a yam at all, but rather a distinct variety of the Ipomoea Batata family. Cultivated for thousands of years in the Western Hemisphere, Sweet Potatoes have become an important part of traditional American cuisine. Over 20 years ago two forward thinking New York chefs created TERRA Chips. From the first moment, people were hooked on the vibrant flavors and delectable crunch that comes from sourcing unique and diverse root vegetables from a select group of farmers. Today, the intimate process of crafting our chips remains with over 20 different varieties and flavors that are truly distinctive by nature.
