Dissolve sugar and water in a 2-quart saucepan over medium-high heat. Bring to a boil and cook for 2 minutes. Remove from the heat and cool.
Peel and seed the cantaloupes. Cut into 2-inch pieces. Puree in a food processor. Strain through a medium sieve. Mix strained cantaloupe juice, sugar syrup, and lemon juice with a wire whisk.
Pour into an ice cream machine. Add some cantaloupe pulp, if desired. Freeze to a smooth consistency, according to manufacturer's directions.
You may wish to place in the freezer compartment of your refrigerator for a few hours to harden. Serve in a dessert glass topped with whipped cream or with a scoop of vanilla ice cream. Garnish with fresh mint leaves.
