Steps

1. Make 4-5 deep cuts across the Pork Shoulder Loin (for Tonkatsu) 2 slices, being careful not to cut straight down but at an angle. (This is the key!) Cutting the sinew this way will tenderize the meat and help the flavors penetrate better.

2. Use the tip of your knife to aggressively pound the Pork Shoulder Loin to further tenderize it. (This is the key!) Pounding firmly will make the meat more tender and allow the miso to absorb better.
   🕒 02:18
3. Spread 2 tsp of Soy Sauce evenly over the pounded Pork Shoulder Loin.
   🕒 03:38
4. In a bowl, combine 2 tbsp Miso, 1 tbsp Mirin, 1/2 tbsp Sugar, 1 tbsp Grated Onion, and 1 piece Grated Ginger. Mix well to create the miso marinade. (This is the key!) Adding grated onion helps the marinade cling well to the meat.
   🕒 03:59
5. Spread the prepared miso marinade thinly and evenly over the Pork Shoulder Loin. (This is the key!) Leaving a little marinade behind is important for the later steps.
   🕒 05:02
6. Seal the Pork Shoulder Loin coated with miso marinade, removing as much air as possible, and let it marinate.
   🕒 05:36
7. Slice the leek into very thin diagonal pieces.
   🕒 05:58
8. Soak the sliced leeks in water to make them crisp.
   🕒 06:11
9. Heat a frying pan and add a little Vegetable Oil.
   🕒 06:26
10. Place the miso-marinated Pork Shoulder Loin into the frying pan while it's still cold, starting with the side that will be eaten facing up. (This is the key!) Starting with a cold pan helps prevent the meat from shrinking as it cooks.
    🕒 06:48
11. As soon as you hear a sizzling sound from the meat, immediately cover the pan and reduce heat to low to steam-grill. (This is the key!) Steaming on low heat ensures the meat cooks through and remains tender.
    🕒 07:01
12. Once the edges of the meat turn white, remove the lid and wipe away any excess oil that has accumulated.
    🕒 07:41
13. Flip the meat over.
    🕒 07:51
14. Add 1 tbsp Cooking Sake to the reserved miso marinade and stir-fry it in the pan to create a sauce. (This is the key!) Stir-frying enhances the miso's flavor as a seasoning and reduces excess moisture, leaving a rich miso taste.
    🕒 08:01
15. Gently cook the other side of the meat, scraping up any browned bits from the pan and allowing the meat to absorb the miso.
    🕒 09:00
16. Plate the finished Grilled Pork Miso.
    🕒 09:19
17. Drizzle the prepared sauce over the pork and garnish with the well-drained leeks.
