Step 1

Combine orange juice, elderberry syrup, lemon juice and turmeric in a cocktail shaker. Add ice to make the shaker 3/4 full. Cover and shake until chilled, then strain into a rocks glass filled with ice. (Alternatively, for a layered look, shake the citrus juices and turmeric and strain into a glass filled with crushed ice. Drizzle the elderberry syrup over the ice.)

Step 2

Top with sparkling water and garnish with an orange slice, if desired.
