Mix the butter, chives, ginger, lemon juice and soy sauce and set aside.
Preheat a grill or grill pan. Season the salmon with s & p and rub with the oil. Wipe the grill grates clean and rub with a paper towel dipped in oil. Add the salmon skin side down and cook for 4-5 minutes, until the skin is lightly charred and crisp.
Flip the fish and cook for another 2-3 minutes on the flesh side until the flesh flakes with gentle pressure from your finger but is still slightly translucent in the middle. (This will cook it to medium for well done leave it on another 2-3 minutes).
Serve the salmon with a generous spoonful of the flavored butter, which should melt on contact.
