Here’s how to create perfectly grilled mackerel:

1. Prepare the Marinade: In a bowl, mix olive oil, soy sauce, lemon juice, grated ginger, and minced garlic.
2. Clean the Fish: Rinse the mackerel under cold water and pat dry with paper towels.
3. Marinate: Place the cleaned mackerel in a shallow dish and pour the marinade over the fish. Ensure all surfaces are well-coated. Cover and refrigerate for at least 20 minutes.
4. Preheat the Grill: Heat your grill to medium-high. If using a charcoal grill, prepare a two-zone fire for even cooking.
5. Season the Fish: Remove the mackerel from the marinade and season with salt and pepper.
6. Grill the Mackerel: Place the mackerel on the grill skin-side down. Grill for about 4-5 minutes per side, or until the fish is cooked through and has nice grill marks.
7. Check Doneness: The fish is done when the flesh is opaque and flakes easily with a fork.
8. Garnish: Once cooked, transfer the mackerel to a serving platter and garnish with fresh coriander if desired.
9. Serve: Accompany the grilled mackerel with lemon wedges for an extra splash of flavor.

These simple steps guide you through an incredible grilling experience, ensuring your mackerel is both flavorful and beautifully cooked.
