This recipe features tender and flaky cod fillets coated in a sweet and savory soy sauce glaze. In a small saucepan, combine soy sauce, brown sugar, garlic, and ginger. Bring the mixture to a simmer and cook until the sugar has dissolved and the sauce has thickened slightly. Place the cod fillets in a baking dish and pour the soy sauce glaze over them. Bake the cod in a preheated oven until it is cooked through and the glaze has caramelized. The result is a deliciously glazed cod that pairs well with steamed rice and steamed vegetables.
