Pat salmon dry using paper towels and place in a food-safe container with lid. Combine brown sugar, salt and pepper in a small bowl and spread evenly over the salmon pieces. Drizzle with liquid smoke. Make sure the fish is coated with the marinade.
Cover tightly and marinate in the refrigerator for 8 hours, turning the fish after 4 hours. ( It’ll still be fine if you forget this step )
Take the fish out of the fridge. Discard liquid and transfer to a greased baking tray or line it with parchment ( I used a 12x18 cookie sheet ).
Preheat the oven to 375F. Spray some oil on top of the fillet then bake for 20 - 25 minutes. Fish will flake easily once cooked.
Switch to BROIL (High) then cook for about 3 - 5 minutes. Ends and fatty parts will start to caramelize (see images above). Watch carefully to avoid burning the fish.
Remove from the oven and serve with rice and vegetables of your choice on the side.
Notes
* Oven temperatures vary so watch the salmon especially after the first 20 minutes of baking.** Use leftovers ( if any ) in place of regular tinapa for your Pancit Palabok.
