Remove the membrane off the pork ribs. Pour 700ml of water in the Instant Pot and let it boil by pressing the Saute function and setting it to More. Once the water is boiling, dunk the ribs in the pot and let them boil for around 5 minutes to remove the scum off the meat. Take pork ribs out of the Instant Pot and discard the remains.
Add all the listed ingredients in the Instant Pot.
Close the lid and set the Meat function to High for 45 minutes.
Once cooking is done, wait 10 mins for natural release pressure, open the lid and serve soup in bowls garnished with coriander leaves (optional). Serve with rice and a side of Kecap manis and Thai chilies for dipping.
