In a large pot, bring the chicken bones and water to a boil on high heat.
Once the water comes to a boil, reduce the heat to low and simmer for 1 1/2 hours.
For a clear broth, skim the foam and bits off the surface of the soup.
Cook the rice
While the chicken bones are simmering, cook your rice. (I use a rice cooker, but if you don't have one, you can cook the rice on the stovetop.)
Prepare the broth
After 1 1/2 hours, remove the chicken bones.
Skim off any additional foam and fat.
Increase the heat to high. Once it comes to a boil, lower heat and simmer the broth until it reduces by 1/3 the original volume (~20 min depending on the volume of soup.)
Once the broth has reduced, add your cooked rice and simmer on med-low for another 20 mins or until the desired consistency is achieved.
Serving
Top porridge with thinly sliced green onions, white pepper, and diced century egg.
