Peel and core the apples, cut them into medium-ish sized chunks. You don't need to be super precise as the blender will be doing the hard work of pureeing them anyway!
Place the water into the bottom of the Cooking Blender, first. Then add the apples. Place the lid on the unit and make sure it's secured to the base.
Set the machine to "jam" setting.
After the first cooking cycle, the unit will beep. Remove the clear lid vent cap and add the stevia, cinnamon, and ginger. Press the start button to tell the unit you're ready for it to start cooking again.
At the end of the cycle, pour the apple butter into a container to cool at room temperature. Once cooled, cover it and place it into the fridge.
