Never underestimate black peppercorns! Their heat sneaks up on you in this turmeric tonic.
- 1 4-inch piece peeled ginger, coarsely chopped
- 1 4-inch piece peeled turmeric, coarsely chopped, or ½ teaspoon dried turmeric
- 2 teaspoons black peppercorns
- Thyme sprigs (for serving; optional)
Blend ginger, turmeric, honey, lime juice, black peppercorns, and 3 cups water in a blender until smooth. Strain through a fine-mesh sieve into a large bowl. Stir in chia seeds and let sit until seeds begin to swell, 8–10 minutes.
Divide tonic among ice-filled glasses. Top off with club soda and garnish with thyme sprigs, if desired.
Do Ahead: Tonic can be made 1 day ahead. Cover and chill. Stir vigorously before topping off with club soda.
