Bring 8 cups of water and the elderberries to a boil in a saucepan.
Simmer for 15–20 minutes.
While that is simmering, add hibiscus, clementine, lemon, mint, and ginger to a large glass jar with a cover. Set aside.
Remove the saucepan from the heat once finished, and strain out the elderberries.
Pour the elderberry-infused water into the glass jar, making sure all the ingredients are submerged.
Cover and place in the sun to steep for 2–4 hours, depending on how strong you prefer it.
Once finished, transfer to a pitcher filled with ice cubes and additional garnishes of fruit and mint. Alternatively, refrigerate it in an airtight container to keep it fresh and chilled.
For the best taste, drink within 2 days.
Notes
Boiling the elderberries before preparing the sun tea helps extract the flavors and ensures safety.
