Purple yams go by many names, including purple sweet potato, ube and its scientific name, Dioscorea alata. It is a starchy tuberous root vegetable with brown to greyish skin with a light to deep purple colour. Hence the name!
While its exact origins are unknown, it is commonly believed to come from the islands of Indonesia in Southeast Asia. Purple yam is also an indigenous staple of the Philippines. It can also be found in Malaysia, Brazil, and Caribbean regions such as Venezuela and Colombia.
In North America, while you may be able to find ube in some organic stores, your best bet for finding purple sweet potatoes is at an Asian grocery store.
Purple yam has a distinct sweet and nutty flavour. Professional and at-home chefs alike incorporate purple yam ube into several sweet and savoury recipes, including mashed purple sweet potatoes, purple yam jam, purple sweet potato buns and even ube ice cream and cupcakes!
Personally, among our favourite recipes at Baroness Bubble Tea is our Purple Yam + Organic Milk Tea with delicious brown sugar.
On top of being a delicious treat, purple sweet potatoes also have multiple health benefits!
