1 can (6 ounces) frozen orange juice concentrate, thawed
1/3 cup sugar
1/2 cup instant nonfat dry milk powder
2 teaspoons vanilla extract
3/4 cup cold water
10 to 12 ice cubes
Orange slices and mint, optional
in a blender, combine the first five ingredients; cover and process on high until smooth. Add ice cubes, a few at a time, blending until slushy. Serve in chilled glasses. Garnish with orange slices and mint if desired. Serve immediately.
Editor's Note: For a fancy glass edge, invert glass and dip into orange juice and then sugar; let dry 1 hour before filling glass.
