4. Grill the Fish (8 min)

Pro Chef Tips for Restaurant‑Level Results
- Dry surface = char lines. Pat fish dry; moisture inhibits browning.
- Oil the fish, not the grill. Prevents flare‑ups and sticking.
- 90‑second rotate. For cross‑hatch marks, rotate fillet 90° halfway through first side.
- Use your nose. Mahi‑mahi smells sweet‑briny; any ammonia scent = not fresh.
- Carry‑over counts. Pull at 135 °F; it finishes cooking off‑heat.
