Directions:
1. Cut the cod into pieces and place them into a pan full of water.
2. Leave it in water for 2 to 3 days, changing the water twice daily.
3. After soaking, change the water again and place the cod and water, along with a bay leaf and cook for 30 minutes on low heat, removing any foam that comes to the surface.
4. After 30 minutes, remove the cod from the pan and place in a container with high sides.
5. Remove the skin and the bones from the cod and add 2 gloves of garlic.
6. Take a wooden spoon (or immersion hand blender) and start to mix vigorously, slowly adding the olive oil.
7. The quantity of the oil will depend on the cod itself.
8. Continue mixing until the cod turns light and has a whipped, mousse-like texture.
9. Taste and add salt if required.
10. Serve on fresh cut bread slices or grilled slices of polenta.
11. Sprinkle top with some cracked black pepper.
