Their cuisine often features simple, fresh ingredients, with coconut being a cornerstone. While many Pacific islands boast delicious raw fish salads (like ika mata or poke), this Mai Kaina-inspired recipe offers a cooked, grilled take.

Ingredients

• 1.5 lbs firm white fish fillets (such as mahi-mahi, snapper, cod, or halibut), about 1-inch thick
• 1 (13.5 oz) can full-fat coconut milk or coconut cream
• 1 tablespoon lime zest (from 1-2 limes)
• 3 tablespoons fresh lime juice, divided
• 2 cloves garlic, minced
• 1 inch fresh ginger, grated (about 1 teaspoon)
• 1 tablespoon neutral oil (like avocado or canola), plus more for brushing grill grates
• 1 teaspoon sea salt, plus more for seasoning fish
• ½ teaspoon freshly ground black pepper
• Optional: 1 small sliced red chili (like serrano or bird's eye) for heat, chopped fresh cilantro or scallion greens for garnish

Directions

1. Prep the fish: Gently pat the fish fillets thoroughly dry with paper towels. This is crucial for getting a nice sear on the grill and preventing sticking. Season lightly on both sides with salt.
2. Make the coconut-lime mixture: In a medium bowl, whisk together the coconut milk (or cream), lime zest, 2 tablespoons of the fresh lime juice, minced garlic, grated ginger, 1 tablespoon neutral oil, 1 teaspoon salt, and ½ teaspoon black pepper. This will be your vibrant marinade and glaze.
3. Marinate briefly: Add the dried fish fillets to the coconut-lime mixture, ensuring they are well coated. Let marinate at room temperature for just 10-15 minutes. Longer isn't better here, as the acidity of the lime can start to "cook" delicate fish.
4. Preheat and prep the grill: Preheat your gas or charcoal grill to medium-high heat (around 400-450°F / 200-230°C). Clean the grates thoroughly with a grill brush, then oil them well using a paper towel dipped in neutral oil held with tongs. This is key for keeping fish from sticking.
5. Grill the fish: Remove fish from the marinade, letting excess drip off. Place the fillets directly on the preheated, oiled grill grates. Grill for 4-6 minutes per side, depending on thickness. Resist the urge to move the fish too early; it will release naturally when it's ready to flip.
6. Glaze/brush near the end: During the last few minutes of grilling, gently brush the fish with some of the remaining coconut-lime mixture from the bowl. Be careful not to let the coconut burn; it browns quickly.
7. Finish off heat: Once the fish is cooked through, carefully remove it from the grill. Drizzle with the remaining 1 tablespoon of fresh lime juice immediately. Let the fish rest for 2-3 minutes before serving.
8. Serve: Transfer the grilled fish to plates. Spoon any remaining coconut-lime sauce from the bowl over the top. Garnish with optional sliced chili and fresh cilantro or scallion greens for a burst of freshness. Enjoy your fish seasoning for grilling masterpiece!
9. Doneness Cues (Very Practical)
   1. Internal Temperature: The ideal internal temperature for cooked fish is 145°F (63°C) when measured with an instant-read thermometer at the thickest part.
   2. Visual Cues: The fish should be opaque throughout and flake easily with a fork. It should also have a nice, golden-brown sear from the grill.
   3. Common Mistakes: Overcooking is the biggest culprit for dry, rubbery fish. Always err on the side of slightly undercooked, as it will continue to cook slightly from residual heat after being removed from the grill.
