This is the punch my mom would make for any of her parties when we were growing up and then it was served at all of the weddings in my family. Now I make it for my parties.
4 cups sugar
4 cups water
6 oz. frozen OJ concentrate
1/2 cup lemon juice
46 oz. pineapple juice (from a can)
2 2-liters ginger ale
In a large saucepan, combine all ingredients and warm until sugar is all dissolved. Don't boil. Pour into any freezeable container. Freeze for at least 24 hours.
When ready to serve, pour ginger ale over and scrape the frozen block to make slush.
