Start by juicing the lemons until you have 1 cup of fresh lemon juice.
In a small saucepan, combine the lemon juice, water, and honey (or your chosen natural sweetener)
If you want to add some extra flavor to your syrup, toss in a few fresh mint leaves, slices of ginger, lemon zest or a cinnamon stick.
Heat the mixture over medium heat, stirring constantly until the sweetener dissolves completely. This should take just a few minutes.
DO NOT LET IT BOIL.
Once the sweetener has dissolved and the flavors have infused, remove the saucepan from the heat and let it cool to room temperature.
Once the syrup has cooled, strain it through a fine-mesh sieve.
Transfer the strained syrup to a clean, airtight glass jar or bottle.
Add a few slices of lemons.
Store it in the refrigerator. It should keep for about 2-3 weeks.
