Instructions
-
Cut 1-inch thick fish chunks and generously salt them.
-
Combine oil ingredients in a deep saucepan. Heat the oil mixture over medium heat to 160 F, maintain for 15 minutes, then turn off heat, cover, and cool for 45 minutes.
-
Reheat the oil to 150 F, then add fish in a single layer, ensuring it's fully submerged.
-
Turn off heat, cover, and let the fish steep in oil for 30-45 minutes.
-
Remove fish with a slotted spoon and transfer to a clean container.
-
Cool the oil, then strain it through cheesecloth or a fine mesh. Pour the strained oil over the fish, ensuring it's completely covered and no cooking liquid is included; use fresh olive oil if necessary.
