Grilling a whole fish doesn’t have to be daunting, especially if you use this turning method to minimize the risk of tearing the skin. Lay the fish horizontally across the grill grate with the top fins toward you and cook. When it’s time to turn, wedge two metal spatulas under the fish—one near the tail and the other at the head—then quickly and confidently roll it away from you onto its other side in one fluid motion.
