Grilled (Or Baked) Bluefish

["A little mayonnaise coats the fish to keep it marvelously moist. Use this recipe with any fresh local fish such as bluefish or rockfish.", "Lightly season the fish with salt and pepper, then brush 1 part Dijon mustard and 2 parts good mayo all across the fish's flesh to coat. Add chopped dill, if desired and broil it in the oven for about 6-8 minutes. Or, lay it on some heavy-duty aluminum foil and slip it onto a hot grill, close the cover, and cook until opaque and moist on the inside (again about 6-8 minutes for fish less than 1-inch).", "Shopping Tip:

Keep bluefish cool on the trip home from market and keep it refrigerated in

the coldest part of the fridge until you're ready to use.", "Note:

As migratory marine fish, blues are voracious predators that sport fishermen prize for their fighting ability. In the US, they can be found off the coast of Florida and in the Gulf of Mexico in the winter months and in New England waters from June through October, when they then head south again."]
