In a large stock pot, bring the piloncillo and water to a simmer over medium heat. Stir frequently to dissolve the sugar. Once dissolved, allow the mixture to simmer for 4 minutes. Remove from the stove and allow the mixture to cool to room temperature (or place in the refrigerator to cool completely).
Once the guarapo is cold, add the lime juice. Stir to combine.
Fill a large pitcher with the ice and pour the guarapo mixture over it. Stir to cool dilute the guarapo, then add the lime slices, if desired.
Pour into individual glasses filled with ice.
Guarapo is best enjoyed within 3 days as the mixture may begin to ferment.
