"Goguma Mattang is a Korean sweet potato side dish or snack created by deep frying sweet potato pieces in oil and tossing them in a caramelized syrup. This may be my new favorite way of eating sweet potatoes. They are highly addictive and don’t take much prep work or ingredients. The sweet potatoes end up crisp on the outside, soft and fluffy on the inside, and covered with a sweet honey brown sugar coating."

Step by Step Method

Step 1

Peel the sweet potatoes and cut into about 1-inch pieces. Place in a large bowl and cover with cold water. Allow soaking for 30 minutes. Drain and use a towel to dry the sweet potatoes thoroughly.

Step 2

Fill a large saucepan with enough vegetable oil to cover the sweet potato pieces and place over medium-high heat.

Step 3

Once the oil has reached about 350 degrees F, add the sweet potato pieces and cook until golden the center is softened, 5-10 minutes. Remove with a slotted spoon onto a paper towel lined plate.

Step 4

In a large wok or pan, combine honey, brown sugar, and 1 tablespoon oil over medium heat. Reduce heat to low once it starts to bubble. Toss in the fried sweet potato pieces and continue to cook while gently tossing for 2 minutes.

Step 5

Immediately remove from the pan and transfer to serving plates. Garnish with sesame seeds or chopped nuts.

This was sweet, but not overly sweet. Something I would never feel guilty about eating. I used Sesame seeds.

Wowzers - like eating candy! Even the DH, who doesn't care much for sweet potatoes - went back for seconds. The sauce caramelizes on the sweet potatoes, so you get a nice thick and somewhat crunchy outside, with the smooth and tender inside. Wow - we were in heaven! And will be making these over and over. Thanks for sharing this amazing recipe!

Scaled back for one serve and was wishing I had made more as it was so delicious even though I had overcooked it and it looked slightly burnt but still tasted fantastic so will definitely be making it again. Thank you ForeverMama made for Alphabet Tag Game at FF&F.
