Koreans love sweet potatoes and they enjoy them in every way possible. Sweet potato pizza, sweet potato latte, sweet potato cake and sweet potato chips are all examples of the modern Korean obsession with sweet potatoes. Sweet potato is also very popular as a diet food, as it is filling yet low in calories and high in dietary fiber.

Mat Tang, or Candied Sweet Potatoes, is a traditional way of enjoying sweet potatoes. It is an incredibly delicious side dish that can also be served as a snack or dessert. The sweet candy-like outer layer is perfectly harmonized with the soft texture and wholesome flavor of sweet potato. It’s great for parties if you thread them onto toothpicks or skewers. It can be a great alternative to cookies and candies for kids too.

Soy sauce: can be omitted.
Black sesame seeds: can be omitted or replaced with regular sesame seeds.
Sweet Potatoes:Traditionally, Korean sweet potatoes (also known as koimo sweet potatoes in North America) are used for this recipe but you can also use different species of sweet potatoes, such as yam.

Variation
You can use the same recipe without deep-frying the sweet potatoes. Pan-fry sweet potatoes in vegetable oil on high heat until brown and use the same sauce. It will be similar in taste but will not have the candy-like crispy texture.
