Buta no kakuni is a classic Japanese dish of braised pork belly that is slowly cooked until the meat is tender, juicy, and packed full of umami. It is simmered with traditional Japanese flavors that include soy sauce, mirin, sake, and sugar, with a hint of ginger and scallions.

Pork belly is the cut where bacon originates and is quite heavy in fat, but the extended time that this Japanese-style braised pork belly is simmered with ginger and scallions reduces the fat in the finished dish. The pork is then simmered again in a fresh pot of water and sauce ingredients to season it.

Give Japanese buta no kakuni a try and you might be pleasantly surprised at how a small, tender piece of braised pork belly brightens up the dinner table as an appetizer or side dish. A small piece is also a wonderful addition the next day in a Japanese bento lunch.

  • If you don't have a drop lid, cut out a piece of aluminum foil to fit inside the pot and top with a small plate to weigh down the pork.
  • If you don't have mirin try dry sherry. You can also use a dry white wine, but add a little extra sugar to counteract any sourness.

Why is my braised pork belly tough?

Pork belly contains a lot of fat, so if it is not cooked long enough to render the fat, a lot of chewy fat can be left behind, making it tough. Cook it low and slow for the most tender results, with a quick blast of heat at the end to crisp the skin.

Do you leave skin on pork belly?

The skin is usually left on pork belly since it can become very crispy, balancing the melty fat within. If you are making a larger cut of pork belly, score the skin before you begin to help the fat break down.
