3 c. rhubarb, chopped
1 c. water
1/3 c. sugar
1 c. apple juice
1 (6 oz.) can frozen pink lemonade concentrate, thawed
1 (1 liter) lemon-lime carbonated beverage

In a saucepan combine rhubarb, water and sugar. Bring to boiling. Reduce heat, cover and simmer 5 minutes or until rhubarb is tender. Cool.

In a blender process half of the mixture until smooth. Pour into a bowl. Repeat with remaining mixture. Stir in apple juice and lemonade. Pour into an 8x8x2 inch baking pan. Cover and freeze several hours or overnight until firm.

Before serving, let mixture stand at room temperature for 45 minutes. Scoop about 1/3 cup into each glass. Fill each glass with about 1/3 cup carbonated beverage. Top each serving with a mint sprig (optional). Mixture can be scooped into a punch bowl and add carbonated beverage.
