In a medium saucepan, combine the water, dried elderberries, cinnamon sticks, and ginger (if using).
Heat on medium heat until the mixture starts to boil. Reduce heat to simmer and cover with a lid.
Simmer for about 1 hour, stirring occasionally, until the syrup is reduced by about half.
Remove from heat and allow it to cool for 10-15 minutes. Pour the syrup through a strainer into a glass bowl. Use the back of a spoon to squeeze any remaining juice out of the berries. Discard the elderberries.
Allow the elderberry syrup to cool completely before whisking in the honey.
Add the honey and stir until it dissolves into the mixture.
Pour the completed elderberry syrup into a jar, add a lid, and store in the refrigerator for up to two weeks. For longer storage, freeze syrup in ice cube trays and thaw whenever you need them. Makes about 3 cups of elderberry syrup.
