In a microwave safe bowl, add the peeled corn and microwave for 4 minutes.
Cut the corn in half, and then stand the corn and cut into quarters lengthwise.
Cover with potato starch and dust off the extra potato starch.
In a deep pan, add oil and bring it to 340°F (171°c).
Add 4 of the corn at a time, and fry for 4 minutes. Use chopsticks to turn the corn and make sure every surface is fried.
After 4 minutes in the oil, move to a wire rack to drain excess oil.
After you fry all the corn, prepare a medium pan.Turn the heat to medium, and add butter, soy sauce, and sugar. Add the fried corn into the pan. Stir everything well!
