Vodka Mixed Berry Granitas

Rinse berries and drain well. Layer strawberries and raspberries in a 2-quart glass jar. Top with orange slices and blackberries. Pour vodka over berries until fruit is covered, then cover the jar. Save the empty vodka bottle. Let berries macerate in vodka for three to six days. Strain the berries from the vodka, then pour vodka back into the saved bottle. Water Puree berries and strain through a fine mesh strainer. Pour strained berry juice into large measuring cup. Measure the juice, then add an equal amount of water. Pour into bowl. Whisk in sugar to taste, at least 1 1/4 cup, and stir until dissolved. Pour into a baking pan measuring 9 by 13 by 2 inches and place in freezer until ice crystals form, about 30 minutes. Use a fork to break up frozen crystals. Continue freezing and stirring every 30 to 45 minutes until mixture is completely frozen and ice crystals are uniform in size. Scoop crystals into goblet and garnish with mint or extra berries. Serve immediately. Serves 4 to 6.
