Combine all ingredients except for the coriander leaves in the pressure cooker. Set mode mode to STEAM KPT7 and the vent knob at SEAL. Alternatively you can use a large sauce pan and simmer till reduced.
After the 7 minutes is up, release the pressure manually. Set mode to BAKE CHICKEN and allow it to continue to simmer for about 10 minutes or until all the excess liquid has evaporated. Remember to stir occasionally to prevent the bottom from getting burnt.
Finally stir in the coriander leaves.
Let it cool before used as fillings.
