• Lemon-lime soda for serving

Directions

1. Wash the rhubarb thoroughly and chop it into small pieces.
2. In a large pot, combine the chopped rhubarb and water.

6. Add the strawberry gelatin, lemon juice, and frozen pink lemonade concentrate. Whisk everything together until smooth and well combined.
7. Cover the container tightly and place it in the freezer overnight, or for at least 24 hours.
8. Before serving, remove the slush from the freezer and stir it to loosen the texture.
9. Scoop the slush into glasses and top with chilled lemon-lime soda. Stir gently and serve immediately.
