Peel, core and quarter the apples. You may leave the peel on, I just like them removed. Transfer apples to the inner pot of the IP along with water. Add cinnamon powder and nutmeg powder. Close the lid of the IP. Press manual button and cook on high pressure for 7 minutes. Once done, wait for additional 6-7 minutes and then release the remaining pressure manually. The apples will be thoroughly cooked by then. Your applesauce is done. If you prefer a smooth consistency applesauce, you may blend the sauce using an immersion blender at this point (I did this). Let the applesauce cool completely and then store it an airtight container in the refrigerator.
