Pour the elderberries and water into a saucepan and simmer for 20 minutes with the lid on.
Remove the lid and simmer for another 15 minutes or until the liquid has reduced by about half.
Pour the syrup into a bowl using a fine mesh strainer to catch the elderberries. Press any excess fluid out of the elderberries.
Optional: Return the syrup to the pot on low to medium heat. Finely sprinkle in the arrowroot powder while whisking rapidly and cook for another 3 minutes or until thickened. Do not overheat, as the arrowroot powder will begin to break down.
Remove from heat and let the syrup cool fully, as the hot syrup will kill some of the beneficial components of the raw honey you will be adding. I usually place the syrup in the refrigerator to cool faster.
Stir in the raw honey.

Notes
-*Feel free to adjust the honey to your desired level of sweetness. 1/2 cup will make a highly sweet syrup. For a vegan option, substitute maple syrup.-*1 tsp arrowroot powder for minimally thick, 2 tsp for more traditionally thick.-Substitute other thickeners such as corn starch as desired.
