- d.Pour the marinade over the fish, turning each fillet to ensure it's evenly coated.
- e.Let it marinate at room temperature for 15-20 minutes. Do not exceed 30 minutes, as the acid in the lemon juice will start to break down the fish protein and make it mushy.

What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Patting the fish dry before marinating is essential for achieving a good sear and beautiful grill marks.
- 2Do not over-marinate! The citrus juice will 'cook' the fish (like ceviche) and result in a mushy texture if left for more than 30 minutes.
- 3A hot, clean, and well-oiled grill is the secret to preventing delicate fish from sticking. Don't skip this step.
- 4Resist the urge to move the fish once it's on the grill. Let it cook undisturbed to develop a crust, which will help it release easily when it's time to flip.
- 5To check for doneness without a thermometer, insert a fork into the thickest part and gently twist. The fish should flake apart easily.
