Mackerel is a fatty fish that is packed with omega-3 fatty acids and has a rich, distinctive flavor. In this recipe, the mackerel fillets are glazed with a mixture of soy sauce, honey, garlic, and lime juice, then broiled until the glaze is caramelized and the fish is cooked through. The result is a dish that is both sweet and savory, with a deliciously crispy exterior. Serve the soy sauce glazed mackerel with a side of steamed vegetables or a fresh salad for a nutritious and flavorful meal.
