This keeps well in a dark bottle like amber in a cool place for months. This is just a simple recipe with 3 ingredients. Small batch. 1/4 cup dried elderberries or 1/2 cup fresh. 1 and 1/2 cups filtered water (I used our good fresh well water) 1/3 cup raw honey. Place elderberries and water in a pan and bring to a boil watch and stir, and then turn heat down so it can simmer 25 to 35 minutes. Strain the juice out into a bowl and mash berries to get all you can out of them. Add your honey and cool. Put into dark or amber glass bottles. 1 teaspoon one or two times a day for maintenance. When ill 3 teaspoons 4 times a day 1/2 that for children. You can dilute this with water for young children.
