One whole, 3½-pound snapper should serve two to four people, so if you have a larger crowd, increase your recipe accordingly. For presentation, either bring it to the table on the baking tray, or use two spatulas to gently move the fish to a platter, being careful not to break off the tail section. Serving is easy: begin flaking the cooked fish into portions from one side then pull out the center bone and serve the remaining fish on the second side.
