The purpose of marinating most meat is twofold. First, marinades add flavor. Secondly, the acids, such as lemon or lime juice, tenderize a tough cut of meat. Because fish already is tender, do not leave it in an acid-based marinade for more than one hour. The acid literally will cook the fish without heat. When overly marinated fish is then cooked, it becomes mushy and has a tendency to fall apart. There is a simple way to infuse your fish with flavor while avoiding this potential pitfall when marinating overnight.
Things You'll Need
Inspect the fish for any bones and remove if them if necessary.
Rinse the steaks or fillets briefly under cold water and pat dry with a paper towel.
Spray the fish with a coating of cooking spray or massage lightly with extra virgin olive oil. This prepares the fish to receive your marinade.
Sprinkle the oiled fish with an herb or seasoning blend of your choosing. This method is called a dry marinade in contrast to a wet marinade that typically has an acid base. Sprinkle with salt and pepper if desired.
After applying a generous coating of the seasoning you choose, rub the fish gently to work the flavors into the individual pieces.
Place the fish in a large resealable storage bag or container. The pieces do not need to be in a single layer. If the pieces overlap, it simply exposes them to more of the dry marinade.
Refrigerate, preferably no longer than 24 hours. Cook the marinated fish as desired.
Select the freshest fish available. Fresh fish should not have an overly fishy smell and should not have a sticky or slimy texture. When fresh is not an option, choose frozen. Most commercial frozen fish is processed and frozen right on the boat.
Ideal seasoning choices for your marinade include lemon pepper, Cajun, Old Bay and chipotle. Fresh herbs also add flavor without affecting the integrity of the fish. Choose herbs such as cilantro, basil, tarragon, thyme or dill.
For a single-step dinner, prepare your fish using this method and then wrap it in individual foil packs with vegetables. It will marinate in the foil pack. The next day, bake it in the oven or on the grill for 15 to 30 minutes, or until done.
