Marinate the fish briefly while the grill heats.
Let the seasoned fillets sit at room temperature for 10 minutes. This gives the flavors a chance to penetrate without acid over-cooking the fish.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the mahi-mahi fillets bone-dry before brushing with marinade to ensure a good sear.
- 2Let the fish marinate no longer than 10 minutes; the lemon juice can begin to cook the delicate flesh.
- 3Heat the grill to medium-high (about 400°F) and oil the grates well to prevent sticking.
- 4Place fillets at a 45° angle to the grates for attractive cross-hatch grill marks.
- 5Don't move the fish until it releases easily from the grates — forcing it will cause tearing.
- 6Use an instant-read thermometer: mahi-mahi is perfectly cooked at 137°F; it will carry over to 140°F.
