Rhubarb Slush (Jill Woolf's)

3 cups chopped fresh or frozen rhubarb
1 cup water
1/3 cup sugar
1 cup apple juice
1 (6 oz) can frozen pink lemonade concentrate- thawed

In a saucepan combine the rhubarb, water and sugar. Bring to a boil, reduce heat, cover and simmer for about 5 min. or until rhubarb is tender. Cool for about 30 min.
In a food processor or blender, puree mixture, half at a time. Stir in apple juice and lemonade. Pour into a container and freeze until firm.
To use- let stand about 30 min. before serving (or use microwave). Scoop into glass and add soda (7-Up, Sierra Mist or any lemon-lime type pop) Enjoy!

PS Jill always doubles this.
PSS Can use diet soda. I did and you could not even tell it was diet. Which is remarkable because I do not like diet sodas.
