In a small saucepan over medium heat, add oil and when oil is heated, add scallions and salt. Stir and cook for a few seconds until fragrant and scallions are soft, then transfer the scallion oil to a clean bowl.
Use an oyster knife to shuck the oysters and put on a wired rack.
Heat a grill pan, gas grill or charcoal grill to medium high – high heat. Place oysters on the grill, close the grill or cover the grill pan and cook for about 2 minutes.
Open and top each oyster with ½ teaspoon – 1 teaspoon scallion oil. Cover and cook for another 1-2 minutes until just cooked through. Cooking time depends on the size of the oysters.
