Frozen purple yam, also known as frozen purple sweet potato, refers to the vibrant-colored tuber that has been harvested, cleaned, cooked, and then frozen to preserve its unique flavor, texture, and nutritional value. Purple yam is a root vegetable with a distinct purple or deep violet flesh, which sets it apart from other varieties of yams or sweet potatoes.

It can be added to desserts, baked goods, smoothies, ice creams, and other sweet treats, imparting its vibrant color and subtly sweet taste. It can also be incorporated into savory dishes like soups, stews, curries, or used as a colorful ingredient in salads.
