Soak the salt cod in water for 24 hours, changing the water a few times.
Taste the fish. It should be neither too salty nor too waterlogged.
Place the salt cod in a stainless steel bowl with the skin side up. Heat some olive oil with the garlic, peppercorns, bay leaves, and thyme to 150°C (300°F) and pour over the salt cod. Allow to cool to room tempe
