Note: Penn Herb Co. is a great, and economical, source of Cinchona Bark. For the other ingredients, look in the bulk spice area of your local grocery or health food store. For the bottles, One Kings Lane is a good source. Note: Dry ingredients are listed by weight, liquid ingredients are listed by volume.

  • Make rich simple syrup: dissolve 3 cups sugar in 1 1/2 cups water over medium heat until sugar is completely dissolved. Allow to cool. Transfer to a container and refrigerate.
  • After 72 hours, strain tonic mixture into a large glass pitcher. Strain tonic a second time, using a coffee filter or very fine cheesecloth.

For the Ultimate Gin & Tonic

  • Fill a highball glass with ice. Add 1 tablespoon tonic syrup, 2 ounces gin, and 2 ounces sparkling water. Stir to combine. Serve with a lime wedge (about 1/6 of a fresh lime). To drink: squeeze the lime wedge into the drink, then drop it in. Enjoy!
