Combine soy sauce, honey, miso paste, ginger and garlic in a bowl and whisk well.
Place marinade and salmon in a Ziplock bag and refrigerate and marinate everything for at least 30 minutes or over night.
I prepare something looking like a boat out of Aluminium foil but of course you can also line a pan with foil.
Preheat a heavy pan with just a tiny bit of peanut oil. Once your pan is extremly hot sear the top of the salmon for about 1 minute or until you have a nice crust.
Immediatle transfer your salmon to your prepared aluminium foil boat. Flip salmon so the crisp side is faced up.
Bake your salmon in your preheated oven by 180 C (350 F) for 15-20 minutes (depending on thickness). Baste salmon with the sauce halway through.
Pour marinade out of the Ziplock bag into a sauce pan. Bring sauce over medium high heat to a boil and simmer for about 5 minutes until reduced.
