Preheat grill to high heat. Cut one lemon into thin slices for garnish. Cut remaining lemons in half. Grill the lemon slices and halves until they begin to caramelize. Cool. Set aside the slices. Squeeze the juice out of all the lemon halves through a strainer into a medium bowl. In a large bowl combine the honey hot water and sugar. Stir until dissolved. Add reserved lemon juice and cold water. Stir well. Pour into a serving pitcher. Garnish with mint sprigs and reserved lemon slices.
