Preparing for Frying: Heat vegetable oil in a medium, heavy-bottomed pan or deep fryer to a temperature of 375 degrees Fahrenheit.
Coating Mixture: In a small bowl, whisk together the buttermilk and egg until well combined.
Coating Procedure: First, roll each potato ball in flour, ensuring a light, even coat. Subsequently, dip the floured balls into the buttermilk and egg mixture, and finally, roll them in the Panko breadcrumbs to achieve a consistent outer layer.
Frying: Carefully place the coated potato balls into the hot oil. Fry them until they achieve a golden-brown coloration, indicative of a crisp exterior.
