Remove any additional scales from the gutted fish and wash in a bath of vinegar or lemon juice and water.
Cut fish into steaks.
Combine all seasonings, including onion and two kinds of peppers, in a food processor to ensure consistency.
Mix about half of the seasoning mix with about half of the broth.
Pour some of the mixture over fish steaks in a mixing bowl. Apply (rub or brush) the mixture to all surfaces of each piece.
Place fish steaks in a refrigerator to marinate for 20 minutes.
Preheat oven to 350°.
Remove fish from refrigerator and place in a baking dish. Put in the oven to bake for 10 minutes.
After 10 minutes remove from oven.
Add the rest of the broth to the remaining seasoning mixture. Pour the mixture over the fish, evenly distributed so it will create a sauce during baking.
Cover with the dish with foil paper and return to the oven to bake for another 20 minutes.
Remove fish from oven and remove foil paper. Replace fish in the oven for another 10 minutes.
