Raspberry Slush For A Crowd

3 packets unsweetened raspberry punch powder
4 cups sugar
4 cups warm water
1 46-ounce can pineapple juice
1 12-ounce can frozen lemonade concentrate
1 6-ounce can frozen lemon juice
3 20-ounce bags frozen raspberries
1 2-liter bottle lemon-lime soda

In a 3 gallon container, dissolve raspberry punch powder in sugar in warm water. Add pineapple juice, lemonade concentrate, lemon juice, frozen raspberries, and enough water (about 3 1/2 quarts) to make 2 gallons punch. Stir until blended. Pour mixture into large freezer containers and freeze. When ready to serve, thaw mixture until slushy. Pour mixture into punch bowl or individual punch cups and add lemon-lime soda. Makes 75 half-cup servings. PS: I omitted the frozen raspberries and served it in individual glasses, not a punch bowl. I also added a titch of almond extract...Enjoy!
