Make the honey-ginger mix: Grate the ginger. In a small cup, stir 2 tablespoons honey with 2 tablespoons hot water until smooth.
Add the ginger and let it steep for 5 minutes. Strain if you prefer a smoother drink.
Juice the citrus: Squeeze the orange, lemon, and lime. You’re aiming for about 1/2 cup total juice.
Strain out seeds and most pulp.
Build the base: In a shaker or jar, combine the citrus juice with the honey-ginger mix. Add a handful of ice and shake for 10–15 seconds to chill and dilute slightly.
Pour and top: Fill a tall glass with fresh ice. Strain the mixture into the glass.
Top with 4–6 ounces chilled sparkling water, depending on how strong you like it.
Garnish: Add a slice of orange or lemon, a sprig of mint, and a quick twist of citrus zest. For a flavor pop, finish with a tiny pinch of sea salt.
Taste and adjust: If you want it sweeter, add a drizzle more honey mix. For more zip, squeeze in extra lemon.
