• Sup Tulang ready-mix paste.
  1 or 2 packets (depending on how strong you wish the soup to be).
  I use Adabi brand Sup Tulang paste:
   

2. Method

• Wash the ribs.
   
• Place the ribs in a saucepan or pressure cooker.
   
• Add water to twice the depth of the ribs (you can judge how much water to add according to how much soup you wish to end up with).
   
• Slice the onions and then add to the ribs.
   
• Add coarse ground Black Pepper according to taste.
   
• Bring everything to the boil and then lower the heat to let the soup simmer.
  In a saucepan you will probably need to simmer for some two hours or more to get the meat on the ribs to become tender.
  In a pressure cooker set at 15 pounds per square inch, I find that cooking for some 30 minutes will result in tender meat.
   
• Halfway through the simmering time, add the sup tulang paste.
  At this time also add as much cubed potato as you would like.
   
• Cook until the end of the set time and then test the potatoes and meat for doneness.
   
• Adjust your soup with condiments.
  Your main condiment will be salt.
  I used fish sauce.
   
• Garnish with chopped coriander leaves.
   
• Serve hot.
   

ENJOY!
