Boil the pork spare ribs in a medium-sized stockpot for 2-3 minutes to draw out the impurities.
Strain and rinse the pot and the pork ribs well. Be sure to wash them clean of impurities.
Put the pork ribs back in the cleaned stockpot and add 4 cups of water along with garlic. Bring to a boil. Cover then lower the heat and simmer for about 45 minutes or until the pork ribs are fall-off-the-bone tender.
Add in dried wakame and simmer until the seaweed is fully reconstituted, about 2-3 minutes
Season with salt and white pepper to taste. Garnish Chinese Pork Rib Soup with cilantro.
