Equipment

  • citrus press optional, makes it easy to juice lemons.
  • Pitcher
  • wooden spoon

Ingredients

  • 1 cup Swerve granulated sweetener or granulated sweetener of choice
  • 7 cups Water divided
  • 1/8 tsp Xanthan gum or glucomannan  (optional- makes the syrup a tiny bit thicker, can be left out.)
  • 1 1/2 cups Fresh squeezed lemon juice about 8-10 lemons

Instructions

  • In a saucepan over low heat, combine the sweetener and water. Heat, stirring occasionally until the sweetener is dissolved.
  • If using xanthan gum, sprinkle it while whisking at the same time to avoid any clumps. Once it’s all stirred in, remove from heat, cool completely.
  • Juice the lemons making sure to strain out the seeds. A citrus press works perfectly.
  • Add the fresh squeezed lemon juice to a pitcher along with the simple syrup if using) and 6 cups of cold water. Chill and serve over ice.

Notes

  • You can adjust the amount of sweetness based on your preference; for tarter lemonade, try less simple syrup. Experiment and make it your own.
  • Use really cold water if you want to serve this immediately, otherwise chill until it's nice and cold. Alternatively, serve it over ice.
  • You can make the syrup ahead of time to save on time. Allow it to cool to at least room temperature, even better if it's chilled.
  • Make extra syrup and use it in cocktails or Mocktails. It will keep for about a week in the fridge. Because it's sugar free there is no preservative factor to it.
  • The xanthan gum is optional; this is a natural thickener. If you don’t have this ingredient it’s totally fine to leave it out.
