In a large pot, add water and 4 heaping tablespoons of coarse salt. Once the water begins to boil, add the tuna slices, turn off the heat, cover the pot, and let sit for 30 minutes. The fish will cook with the residual heat of the water without falling apart.
Remove the tuna from the water and place it on absorbent paper. If any skin, bones, or dark parts remain, remove them carefully until the fish is completely clean.
Gently place the tuna pieces into wide-mouth glass jars, being careful not to fill the jars to the brim.
Cover the tuna with olive oil and let it rest for a couple of hours until the oil settles and no air bubbles remain.
If necessary, add a little more oil to ensure the tuna is fully covered, then seal the jars with airtight lids.
To sterilize the jars, place them in a pot with water, ensuring the bottom of the pot is lined with a cloth to prevent the jars from breaking during boiling.
Completely cover the jars with cold water, ensuring the water level is 5 cm (2 inches) above the jars. Place the pot on the stove and bring to a constant boil for about two hours. If the water level drops, always replenish with boiling water to maintain the correct level until the process is complete.
Remove the jars from the water and place them on a wooden surface to cool completely.
Ensure the jars are completely airtight to prevent spoilage.
Always use high-quality olive oil for the best flavor.
Store the jars in a cool, dark place to extend their shelf life.
Once opened, consume the tuna within 48 hours and keep it refrigerated.
How long can the tuna preserve last?
The preserve can last for about 4 to 6 months if stored properly. Once opened, it should be consumed within 48 hours.
Can I use a different type of oil?
Olive oil is recommended for its flavor and preservation qualities, but you can use other oils like sunflower oil if preferred.
Do I need to sterilize the jars?
Yes, sterilizing the jars is crucial to ensure the preserve lasts and remains safe to consume.
Can I add other spices or herbs?
Yes, you can add whole peppercorns or other herbs like bay leaves for additional flavor.
What should I do if air bubbles remain after adding oil?
Let the jars rest for a couple of hours and gently tap them to release air bubbles. Add more oil if necessary to fully cover the tuna.
