My family doesn't use pork belly, but instead prefers pork loin to make stewed pork chunks.The cooking method doesn't change with either meat, but the loin is more refreshing.
This is my go-to item whenever I buy lots of roast block on sale. It's a luxurious-tasting dish that's great to serve to guests.
You can also use the water from washing rice instead of rice. Adding the flavoring ingredients in 2 steps prevents the meat from hardening. To add color, you could add boiled bok choy or spinach. Adding boiled eggs to the broth will produce flavored boiled eggs!
