Tips for good roasted, and grilled sea bass

To ensure that roasted sea bass is a hit with your guests and tastes exquisite, you can follow a series of tips. Start by buying fresh fish; although you can find cheaper frozen sea bass, the flavor will not be the same. If you choose this option, leave the sea bass to defrost in the fridge the night before preparing it. Fever defrost the fish outside of the fridge as the heat can cause it to ferment.

It is also advisable to marinate the sea bass before cooking them. To do this you should brush them with half a tablespoon of extra virgin olive oil and season them inside and out. If you like a stronger flavor, you can also make a dressing mixture with lime or lemon, oil, coarse salt, pepper and chopped parsley (it can be fresh or dried). It is advisable to leave the sea bass in the refrigerator after seasoning, so that the ingredients can soak into the fish. The seasoning time can be from 15 minutes to an hour.

If you use a barbecue or grill to cook the sea bass, instead of the oven, the flavor will be different. The potatoes should always be baked in the oven following the recipe described above, but they should be left to cook for 40 to 50 minutes. You should prick the potatoes with a toothpick to know when they are ready.

If you prepare the sea bass on the grill, it is important to paint them well and add a little oil to the grill grate to prevent the fish from sticking. Preheat the grill to maximum and grill the sea bass for six minutes on each side, using barbecue tongs rather than a fork to turn the fish. Leave to grill until the skin is golden brown and the flesh is white. You will know the sea bass is perfect if the flesh can be easily pulled apart.

You can also use a long skewer stick and place it inside the sea bass to make it easier to turn and also to make it easier for your guests to eat. You can squeeze lemon or lime over the top once you have removed the sea bass from the grill to give the skin a unique flavor.

Finally, if you prepare the sea bass on the grill, remember to leave enough distance between the grill and the base, otherwise the food may burn quickly.
