Place elderberries and 3 cups water (and optional spices) in a medium saucepan.

Bring to a boil.

Reduce heat to a simmer for 30-45 minutes.

Remove from heat and cool.

Carefully mash the berries using a spoon.

Strain the mixture into a glass bowl, making sure you squeeze all of the elderberry juice out. (Use a strainer or cheesecloth.)

In a separate jar, add 1 cup water and 1/4 cup arrowroot. Fasten tightly and shake until the arrowroot is dissolved.

Pour elderberry liquid back into the saucepan and simmer.

Add the arrowroot +  water mixture and stir.

Once cool again, add the honey.

Shake before using.
