Steps

The sweet potatoes looked a bit tired, but once washed and peeled, they look quite nice.

Cut into large chunks, soak in water to remove excess starch, then pat dry with a clean kitchen towel.

Deep-fry in oil until golden brown. Frying them twice makes them crispier.

Add the sugar, water, and corn syrup (mulyeot) all at once to a pan.

Bring to a bubbling boil over medium heat. At this point, reduce the heat to low.
Do not stir until you are ready to toss the sweet potatoes.

After about 4 minutes, the bubbles will soften and the syrup will turn a light brown.
When it reaches this point, it is ready.

While the syrup is still hot, quickly add the sweet potatoes and toss to coat.

I sprinkled chopped peanuts on top. Toasted sesame seeds are also wonderfully nutty.
