Preheat broiler or grill to high.
Wipe off all but a thin layer of the miso marinade from the salmon (helps prevent burning).
roil or grill fillets about 5–10 min (depending on thickness) until miso edges caramelize and fish flakes easily.
Use an instant read thermometer: ~125–130°F for medium rare, ~145°F for well done.
Spoon or brush the cranberry glaze over the hot salmon just before serving—don’t broil with it, as sugars may burn. Or serve extra on the side for dipping.
