Warm the tart cherry juice
Pour the cherry juice into a small saucepan. Warm over low heat until just hot—but not boiling.
Bloom the gelatin
Sprinkle the gelatin slowly over the warm juice while whisking constantly to avoid clumping. Continue whisking until fully dissolved (2–3 minutes).
Add the elderberry syrup
Remove the pan from heat. Stir in the elderberry syrup, sweetener (if using), and optional lemon juice.
Pour into molds
Transfer the mixture into silicone gummy molds or a small baking dish lined with parchment.
Chill
Refrigerate for 1–2 hours, or until firm.
Remove and store
Pop gummies out of molds (or cut into squares if using a dish). Store in an airtight container in the fridge for up to 10 days.
