So someone gave us a nice piece of Cobia, any suggestions on how to cook it? Thanks

I found this recipe... Never tried it myself... I've never had Cobia...
I believe it is a rather firm fleshed fish so it should be easy to grill...

[color:"blue"]CARIBBEAN COBIA[/color]

INGREDIENTS:
2 Cobia (or other fish) steaks or filets

For the sweet potato bed:
1 large sweet potato
1 tablespoon lemon juice
2 tablespoons orange juice
1 tablespoon butter
1 tablespoon brown sugar
1 teaspoon salt
1 teaspoon grated fresh ginger

For sweet/hot sauce:
2 tablespoons sugar
1/2 cup water
1/3 cup white wine
1/3 cup diced onion
1/3 cup diced bell pepper
1/3 cup diced carrot
2 tablespoons butter
1 tablespoon habenero hot sauce (or to taste)
1 teaspoon dried thyme

DIRECTIONS:
Cook sweet potatoes your favorite way until tender (bake, boil, nuke or steam). Mash with the remaining sweet potato bed ingredients.

While potatoes are cooking, combine first 6 ingredients for the sauce. Reduce until the sauce is about 1/3 its original volume, then add hot sauce, thyme and butter and simmer for 2 minutes.

Salt and pepper fish and grill until just done.

To serve, spread the sweet potatoes on the plate, place grilled fish on top, then spoon on a generous amount of the sweet/hot sauce.

We have taken depending on the size of cobia...equal parts of blue cheese/and mayo. Mix together smother over fish and drizzle with a little butter. Cover bake @350 for about 1/2 hour. Delish!!!

That sounds like something I make for salmon... but I add copious amounts of dill...

Pretty much any white fish is delicious this way:

Thinly slice a lemon and an onion and lay on a piece of foil large enough to wrap your fish. Top with the fish, season with salt and pepper, and any fresh herb you like. Drizzle with olive oil and a splash of vermouth. Seal the foil, place on a baking sheet and bake at 350 for around 20 minutes, depending on the thickness of the fish. For a fancier presentation, use parchment instead of foil. If you slice the lemons thinly enough, you can actually eat the lemon slices, peel and all, along with the fish and onions.

Another foil or parchment method is to use frozen lima beans in place of the lemons and onions in the above recipe. Same process.
