2 pkgs. (3 oz.) Jello
2 c. boiling water
4 c. cold water
2 (46 oz.) cans unsweetened pineapple juice
2 c. sugar (or 1 1/2 c.)
7 qt. 7-Up or ginger ale

Dissolve flavored gelatin in boiling water. Stir in cold water, juice and sugar. Stir until sugar dissolves. Pour into 3 (1/2 gallon) containers. Freeze until firm.

Two hours before serving, remove cartons from freezer and let stand to thaw at room temperature. To serve, place blocks in punch bowl and break apart with a fork. Add 1 quart 7-Up for each 1/2 gallon of punch base. (Do NOT use ginger ale with lime Jello because it changes color.) Serves 59 (4 ounce).
