Cook The Pork
Combine the garlic powder, sugar, oil, fish sauce and soy sauce in a mixing bowl. Add the pork and marinate for an hour. Put a cast iron griddle pan over a high heat and get it smoking hot. Transfer the pork, wiping off any excess marinade, to the pan and cook for 2 minutes each side, until it’s a deep golden brown and just cooked on the inside (you can slice it to check if you want).
