Elderberries are usually the last berries to ripen in the summer (sometimes alongside some late to the party blackberries). The bushes grow wild across much of southwestern Ohio, but the ones I used for this syrup are from a cultivated patch.
Elderberry syrup is easy to make. You'll combine equal parts elderberries and water in a pot along with sugar in the type and amount of your choice. I usually use honey, adding it as the mixture simmers until I'm happy with the taste. Bring the elderberries and water to a boil, then lower to a simmer until the mixture is reduced by half or a little more. Strain and store in the fridge for adding to all sorts of things. I like to add it to iced tea along with a little sprig of mint from my garden. Enjoy!
