For an extra layer of flavor, consider adding a pinch of red pepper flakes to the caramel sauce for a subtle kick. Serve this Caramel Cod with a side of steamed jasmine rice, roasted vegetables, or soba noodles for a complete and satisfying meal. Ensure the skillet is hot before adding the cod to achieve a beautiful sear and prevent sticking. If you don't have rice wine vinegar, apple cider vinegar can be used as a substitute. The cooking time may vary slightly depending on the thickness of the cod fillets; adjust accordingly.
