Marinate the Cod: In a bowl, whisk together the honey, turmeric powder, minced garlic, grated ginger, lemon juice, olive oil, salt, and black pepper. Place the cod fillets in the marinade, ensuring they are evenly coated. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes, or up to 2 hours.
Prepare the Grill: Preheat your grill to medium-high heat. Lightly oil the grill grates to prevent the fish from sticking.
Grill the Cod: Remove the cod fillets from the marinade and place them on the preheated grill. Grill for 4-6 minutes per side, or until the fish is cooked through and flakes easily with a fork.
Make the Lemon Butter Sauce: While the cod is grilling, prepare the lemon butter sauce. In a small saucepan, melt the butter over medium heat. Add the remaining lemon juice and a pinch of salt and pepper. Simmer for 1-2 minutes, or until the sauce is slightly thickened.
Serve: Transfer the grilled Honey Turmeric Grilled Cod to a serving plate. Drizzle generously with the lemon butter sauce. Garnish with fresh chopped parsley. Serve immediately and enjoy this healthy and delicious meal!
