Directions

  1. Remove the head, internal organs, and any blood from the tuna. Rinse it thoroughly under cold water. ≈ 2 min
  2. Cut it into 15 cm thick slices. ≈ 8 min
  3. Cook it briefly in salted water.
  4. Thoroughly clean the skin, edges, and any areas with blood. ≈ 8 min
  5. Pour each jar, pour a small amount of oil at the bottom, then fill with tuna. Let it sit for 12 hours: the tuna will absorb some of the oil; then add the remaining oil and close the jars.
  6. Place the jars in a large saucepan lined with a dishcloth, cover them with water that is 10 cm (4 inches) above the jars, and then cook for 90 minutes over low heat.
  7. The following day, repeat the same procedure for 30 minutes.
  8. Store the jars in a cool, dry place, and wait a few months before consuming them. ≈ 3 min
