01 -  In a bowl, mix goat cheese with cream cheese and herbs, if using. 
 02 -  Scoop into 2.5cm (1-inch) balls and roll until smooth. Place on a tray lined with parchment paper. Chill in the freezer for 20 minutes. 
 03 -  Arrange three separate bowls with flour (seasoned with salt and pepper), beaten egg, and panko breadcrumbs. 
 04 -  Roll chilled cheese balls in flour, then dip in egg, and coat with panko. For extra crunch, repeat the egg and breadcrumb steps. 
 05 -  Heat oil in a deep pan to 175°C (350°F). Fry cheese balls in batches for 1-2 minutes until golden. Drain on paper towels. 
 06 -  Preheat air fryer to 200°C (400°F). Spray balls lightly with cooking spray and air fry for 7-8 minutes, shaking halfway through, until crisp and golden.
