Rhubarb Punch

Combine the finely chopped fresh rhubarb and water in a large pot. Bring to a boil over medium-high heat.

Once boiling, reduce heat to medium and simmer for 10 minutes until the rhubarb is very soft and begins to break down.

Stir the sugar into the hot rhubarb liquid until completely dissolved.

Add the frozen lemonade concentrate to the pitcher and stir well until fully incorporated. Allow the mixture to cool to room temperature, about 15-20 minutes.

Once cooled, add the chilled lemon-lime soda to the rhubarb-lemonade mixture and stir gently to combine. Serve immediately over ice in glasses.
