2 pints strawberries, hulled
3 cups sugar
1 48 ounce can pineapple juice
2 6 ounce cans frozen lemonade concentrate, thawed
2 6 ounce cans frozen orange juice concentrate, thawed
1 liter bottle lemon-lime soda
3 cups water
Combine the orange juice lemonade and pineapple juice and stir well.
Bring 3 cups water and sugar to a boil in a heavy sauce pan and boil until sugar is dissolved, about 5 minutes. Let cool. Add the syrup to the fruit juices.
Place the whole strawberries into a ring mold. Pour in enough fruit juice to fill the mold. Freeze. Refrigerate the remaining juice.
When ready to serve, pour the fruit juice into a punch bowl and add the sprite. Float the strawberry ice ring in the punch.
