I wanted to make a rich tasting dish using new potatoes. This is also good with chicken instead of pork belly.

Since a lot of fat will come out of the pork belly, there's no need to add oil. In addition, be sure to remove any excess fat with kitchen paper towels.
Use a piece of kitchen paper as a lid on top of the simmering ingredients just like a drop lid (otoshibuta). This makes it easier for the flavors to penetrate.
The amount of seasonings are approximate, so please adjust to taste. Recipe by Mikikoshi
