Bring a pot of water to a boil and add the pork spare ribs. Once boiling again, remove the pork and rinse with water (to get rid of off-tastes.)
Add 1., 2., and ● into the pot, bring to a boil, and turn the heat down to low.
Simmer over low heat without the lid on for about one hour and a half until the meat is tender. Regularly skim off the scum that appears while simmering.
Season with salt and pepper to taste after it is cooked.
Pour into a bowl, garnish with coriander to taste, and serve.
