Pour fruit juice, such as apricot, cranberry-raspberry, grape, mango, or any other that you prefer, into ice cube trays (unless shaver manufacturer provides a mold for ice). You will need about 1/2 cup juice - 6 standard-size ice cubes - for each snow cone. Freeze until firm, at least 2 hours. Place 5 to 6 juice cubes (or follow manufacturer's recommendations for maximum amount) in a snow-cone maker or ice shaver and process. Lightly spoon shaved ice into a paper cup.
