In a medium saucepan, combine the dried elderberries and water. Bring to a boil over medium-high heat. This step helps to extract the beneficial compounds from the elderberries.

Once boiling, reduce the heat to low and let it simmer uncovered for about 30 minutes. Stir occasionally to prevent sticking. The mixture will reduce and thicken, concentrating the flavors.

After 30 minutes, remove the saucepan from heat. Allow it to cool slightly for about 5 minutes. This prevents burns when straining.

Using a fine mesh strainer or cheesecloth, strain the mixture into a bowl, pressing down on the elderberries to extract as much liquid as possible. Discard the solids.

Return the strained liquid to the saucepan. Add the honey, grated ginger, cinnamon stick, and vanilla extract (if using). Stir well to combine. Honey not only sweetens but also adds its own health benefits.

Heat the mixture over low heat until the honey is fully dissolved, about 5 minutes. Do not boil, as high heat can destroy some of the beneficial properties of the honey.

Remove the saucepan from heat and let the syrup cool to room temperature. This ensures that it will not spoil when stored.

Transfer the syrup to a clean glass jar or bottle. Seal tightly and store in the refrigerator. The syrup can last for up to 3 months when refrigerated.
