If using a cheesecloth, tie the lavender into a sachet. Note: If you're not using a cheesecloth, you can use a fine mesh strainer later on.
Combine water, sweetener, and optional keto honey to a large pot and boil over medium heat under sweetener is dissolved.
Once boiled, remove from heat and add the lavender. Lavender can be in a cheesecloth or loose in the water (you will need a fine mesh strainer later on).
Let the lavender steep for about 15 minutes.
Remove the lavender sachet from the water or pour the water and loose lavender through a fine mesh strainer.
Stir in the lemon juice. Allow to cool and then refrigerate.
Serve over ice.
Enjoy!
