Preheat the oil in a medium-sized pot to 350F (175C).
Drain a can of corn well. Then transfer to a medium-sized mixing bowl. Add all-purpose flour, cornstarch, and salt. Using your hands, toss until every kernel is fully coated.
In a small mixing bowl, whisk 1 egg with cold water until well combined. Pour the egg into the corn and toss to mix well.
Take about 2 tablespoons of the corn mixture and place a cheese cube in the center. Take another 2 tablespoons of corn to cover the cheese. Using the palm of your hands, gently squeeze the corn until it forms a ball.
Using a sieve or slotted spoon, carefully lower the corn ball into the hotel oil. Fry the corn ball for 4 minutes or until golden brown and crispy.
Serve with a side of mayo and chili powder and enjoy!
