Mint Lime Simple Syrup:

  • 3/4 cup granulated sugar
  • 1 1/2 cups water
  • 3 stems fresh mint leaves each with about 8 to 10 leaves
  • Fresh lime peels from 2 limes
  • 6 tablespoons fresh lime juice

Butterfly Pea Flower Tea:



For the Mint Lime Simple Syrup:

  • Add the sugar, water, mint leaves, and lime peels to a medium saucepan over medium heat.
  • Bring to a boil, stirring occasionally, and then remove from the heat.
  • Steep for 10 minutes, and then strain, discarding the mint and lime peels.
  • Cool to room temperature.

For the Butterfly Pea Flower Tea:

  • Add the butterfly pea flowers and hot water to a teapot and steep for 3 to 5 minutes.
  • Strain, and then cool to room temperature.

To Serve:

  • Transfer the brewed and cooled butterfly pea flower tea to a serving pitcher.
  • Pour the mint lime simple syrup into the pitcher with the butterfly pea flower tea. At this point, the drink will change color from bluish to fuchsia because of the acid (lime juice) that’s in the simple syrup.
  • For dramatic effect, add 1 small piece of Turkish cotton candy to each glass and stir.
  • Serve with ice.



  • Serving Temperature: This Polyjuice Potion is delicious served hot or iced.
  • Dry Ice: If you’re wondering, you can add dry ice to a drink! Just be sure to use caution and never handle it directly; use tongs to pick it up. The dry ice will sink to the bottom of a drink, and if you use a 1 to 2-inch piece, it will be gone in about 5 minutes.
