4 cups pure grape juice, pure white grape juice, cranberry juice cocktail or other clear juice.
4 envelopes unflavored gelatin

In a large bowl, sprinkle the gelatine over 1 cup of the juice and allow to stand for a few minutes. Meanwhile, heat the remaining 3 cups of juice until just boiling and pour it over the juice and gelatin mixture. Stir until the gelatin is dissolved.
Pour into a 9 by 9-inch pan and chill until firm, about 3 hours or overnight. Dip the pan briefly into hot water to loosen, cut into squares or use cookie cutters, and serve.
