Cover the container and let it rest in the refrigerator for 30 to 60 minutes. This step is what gives it its characteristic deep flavor. After that time, remove the pork loin and pat it dry with paper towels. Reserve the liquid.

The perfect seal and the sesame coating

Heat a non-stick frying pan over high heat with a few drops of oil. When it starts to smoke, add the tuna. Look for the Maillard reaction : that quick browning that caramelizes the outside, sealing in the juices.
