Take one of the potato balls and flatten it into a small patty using your palm. Place a cheese cube in the center of the patty.
Carefully gather the edges of the patty around the cheese, rolling it into a ball. Make sure there are no cracks, and the ball is well-sealed.
On a wide plate, spread 2 tablespoons of corn flour. Roll each cheese ball in the corn flour to coat them evenly.
If you prefer not to coat them in bread crumbs, you can pan-fry these balls directly.
Transfer 1/2 cup of bread crumbs to a separate plate and set aside.
Prepare a slurry by mixing 2 tablespoons of corn flour with 3 to 4 tablespoons of water in a bowl to create a thin mixture. Alternatively, you can use a beaten egg. If baking, the egg option is recommended.
Dip each corn flour-coated cheese ball into the slurry or beaten egg, ensuring they are moistened. Immediately roll them in the bread crumbs to coat.
For extra crispiness, double-coat the cheese balls by repeating the dipping and breading process.
Place the coated cheese balls on a plate and let them rest for 10 minutes before frying.
