Heat a pot/pressure cooker with the cooking oil.
Fry the onions, then add the garlic and when they are soft (onion slightly yellow), add the coriander powder.
Add the pork, mushrooms and bamboo shoots.
When pork has changed colour, add the black sauce, sugar and 1/2 cup of water.
Add the cinnamon stick and cloves.
When pork is cooked and softened (takes 10 minutes on a pressure cooker), remove from pot.
Serve with steamed rice.
