Berry Rhubarb Fool

In a saucepan, combine rhubarb, sugar, orange juice and salt. Bring to a boil. Reduce heat; cover and simmer for 6-8 minutes or until rhubarb is tender. Cool slightly. Pour into a blender container; cover and blend until smooth. Chill. Just before serving, whip cream until stiff peaks form. Fold rhubarb mixture into cream until lightly streaked. In chilled parfait glasses, alternate layers of cream mixture and strawberries. Garnish each serving with a strawberry and a sprig of mint.
