Step 1: Throw in the milk, leftover rice (brown, white, sticky), dates and cinnamon. Close the lid and seal the vent.
Step 2: Pressure cook on high for 6 minutes, irrespective of the rice you use. The rice you are using here is already cooked so 6 minutes if just perfect to get the right porridge consistency. Manually release the pressure.
Step 3: Serve it warm or allow it to cool and garnish with fresh, dried fruits, nuts or seeds.
