To prepare the pork chops, score the fat along the edges of the pork chops to prevent curling while cooking, then gently pound them with the back of a knife or a meat mallet to tenderize.
To marinate the pork, in a bowl, combine the fish sauce, dark soy sauce, honey, 1 tablespoon of cooking oil, garlic, lemongrass, and shallot, then mix well. Add the pork chops and coat them evenly with the marinade, then transfer to a large zip-top bag or container and let them marinate while preparing the remaining ingredients, or refrigerate overnight for a deeper flavor.
To make the dipping sauce, in a bowl, combine the fish sauce, sugar, water, lime juice, rice vinegar, garlic, chili, and carrot, then stir until the sugar dissolves and set aside.
To make the scallion oil, in a small pan over medium heat, add the cooking oil and scallions and cook for about 30 seconds until fragrant, then remove from heat.
To cook the pork chops, in a large pan over high heat, add the remaining 1 tablespoon of cooking oil and sear the pork chops for about 30 seconds per side until golden brown, then reduce the heat to medium and cook for about 3 minutes on each side until fully cooked through.
To serve, let the pork chops rest for a few minutes, then top with scallion oil and serve with the dipping sauce on the side.
