Wash and peel sweet potatoes. Cut into round slices about half-inch thick.
Heat oil in a pan and deep fry sweet potatoes for about 4-5 minutes or until crisp tender. Remove the fried sweet potatoes from the oil and let them drain on a paper towel-lined plate.
Add brown sugar to the hot oil and melt until it turns into caramel. Return the sweet potatoes to the hot oil and coat well with the brown sugar glaze.
Once the sweet potatoes have reached the desired caramelization, remove them from the oil and place them on a wire rack or paper towel to drain off excess oil. Let them cool for a few minutes before serving. (See Note 1) to serve on a skewers.
Notes
Note 1. Just simply insert bamboo skewers through the center of each sweet potato round, making sure they are secure and won't fall off.
