Homemade Tonic Syrup

Adapted from the New York Times.

Makes 4–5 cups, enough to fill 4, 8.5-ounce swing bottles (pictured here)


4 tablespoons cinchona bark flakes

1 cup (about 5 stalks) sliced lemongrass

Zest and juice of 1 lime

Zest and juice of 1 large grapefruit

24 juniper berries

4 teaspoons citric acid

3 cups granulated sugar

Special equipment

Fine mesh strainer


4, 8.5-ounce swing bottles

Small funnel


In a medium saucepan, combine cinchona bark, lemongrass, citrus zest, citrus juice, and juniper berries with 4 cups of water, and bring to a boil. Lower heat to a simmer, and let the mixture simmer, covered, for 30 minutes. Line a mesh strainer or colander with cheesecloth, and set it over a large heatproof bowl. Pour the hot liquid through the cheesecloth into the bowl.

Return the strained liquid to a medium saucepan over medium heat and add citric acid and granulated sugar. Let the mixture simmer, stirring occasionally, just until the sugar is dissolved, about 2 minutes.

Let the syrup cool slightly, then use a small funnel to transfer into 4 gift bottles. When syrup has cooled to room temperature, put the tops on the bottles. Syrup will keep for a few months in an airtight container in the refrigerator.
