In a small bowl, stir the scallion and ginger together to create a thick paste. In a medium bowl, combine the salmon, wine, oyster sauce, soy sauce, scallion-ginger paste, and pepper, and mix until well combined. Cover with plastic wrap and marinate in the refrigerator for 30 to 45 minutes, then return the bowl to your counter and use your hands to fold in the dill until fully incorporated.
