Brush the pork with olive oil, add a pinch of salt, and place in a sous-vide plastic cooking bag and seal 100% vacuumed.
Cook in a Roner machine over low heat (75ºC) for approximately 4 hours (the total time depends upon the size of the meat).
Once the pork is well cooked, remove it from the Roner and let cool until the meat reaches 2-4ºC.
Cut the pork into twelve portions of 2x3 cm and marinate in a bowl with a mixture of 40 g olive oil and 80 g Seasoned Soybean Paste(Ssamjang) for at least 10 minutes.
Cut the pork jowl into 5-cm long pieces and sauté in a frying pan with a dash of olive oil until golden, crisp, and juicy.
