This recipe is one I found on Pinterest, and here is the link to the original recipe. Since I was doubling it, I used a tablespoon of cinnamon.
1/4 c. water
1 T lemon juice
1 T pure vanilla extract
1 tsp ground cinnamon
(If desired, add sweetener of your choice.)
Core and slice apples into 1" slices. Just leave the peel on.
Place in a slow cooker. Add the rest of the ingredients, stir a bit, and cook on low for 4 hours.
Use a potato masher to make chunky applesauce. Puree in the blender if you prefer a smoother texture.
(On another site, I read that homemade crockpot applesauce would keep in the fridge for 5 days but could also be frozen for up to 3 months.)
