Method:

Soak the Cod: Wash the salted cod thoroughly and soak it in water for at least 36 hours, changing the water every 7-8 hours to remove excess salt. This step is crucial for balancing the fish’s saltiness.

Prepare the Cod: After soaking, remove the water, peel off the skin, and debone the cod. Cut the fish into medium-sized fillets, rinse again, and pat dry with paper towels.

Cook the Cod: Heat olive oil in a large, non-stick pan over medium-high heat. Add the cod fillets and cook until lightly golden on both sides.

Add Wine and Sauce: Pour in the white wine, then add the tomato sauce, salt, and pepper. Cover the pan and simmer over low heat for about 2 hours, allowing the flavors to meld together.

Finish with Garlic and Parsley: Just before the end of cooking, uncover the pan to check the sauce consistency. If there's excess liquid, let it evaporate. Add the garlic and parsley, stir well, and let rest for a few minutes before serving.

Variations:

Vegetarian Option: Substitute the cod with mushrooms or eggplant for a plant-based version.

Spicy Twist: Add a pinch of chili flakes to the sauce for some heat.

Tips:

Be patient with the soaking process to ensure the cod loses enough salt.

Use high-quality olive oil for the best flavor.
