Add your apple sauce to a high power blender such as a Ninja or a Vitamix.
Pour in your blueberries and turn on to pulverize them. When that is well mixed, add your Norm's Farm Elderberry Wellness Syrup and mix again.
Line 2 jelly roll pans with parchment paper. Pour your mixture onto them and using a spatula, spread evenly to ¼ of an inch thick or less. The thicker you leave it, the longer it will take in the oven, so you want it thin, but not so thin that you can see through it.
Turn your oven onto the "warm" setting. Place your pans inside and leave on for 4-6 hours. They are done when they start to pull away from the paper and are no longer sticky or wet feeling.
