In a medium pot, combine your peeled, cored, and chopped apples with fresh or frozen blueberries, water, and honey. Bring to a gentle simmer over medium heat. Cover and cook for 20-25 minutes, stirring occasionally.

Once the apples are soft, remove from heat and let cool for a few minutes. Use an immersion blender to puree until smooth.

Let the applesauce cool to room temperature. Transfer to a sealed container and refrigerate for up to a week.
