Goguma mattang is a traditional sweet treat and side dish originating from South Korea. It's usually made with a combination of sweet potatoes, honey, sugar, oil, and walnuts. The sweet potatoes are cut into cubes, steamed, and deep-fried in oil until crispy.

They're tossed with sugar-honey syrup and chopped walnuts. These candied sweet potatoes are then served warm, and if desired, they're garnished with sesame seeds on top before consumption.
