In a medium saucepan, combine water, mint leaves, and sugar. Turn heat to medium high and stir until sugar has dissolved. Continue to cook until mixture comes to a boil. Reduce to a simmer and cook for 5 minutes. * Let mixture cool slightly then stir in lime juice. Pour mixture into glass baking dish and put in freezer. Every hour or so, scrape mixture with a fork, continuing until frozen, about three and a half hours. *You can also make simple syrup without turning on your stove. For directions, see here.
