A delightful and refreshing beverage combining the tangy flavor of rhubarb with the tropical sweetness of pineapple.
Combine the rhubarb and water in a Dutch oven and bring to a boil.
Cut the rhubarb into small pieces to ensure even cooking.
Simmer the mixture for 15 minutes until the rhubarb is soft.
Stir occasionally to prevent sticking.
Let the mixture cool for 10 minutes, then strain to separate the juice from the pulp.
Press the pulp gently to extract more juice.
Mix the strained juice with sugar and pineapple juice until the sugar dissolves.
Stir thoroughly to ensure the sugar is completely dissolved.
Chill the mixture in the refrigerator until ready to serve.
Cover the pitcher to prevent absorption of refrigerator odors.
Serve the chilled juice over ice cubes and top with sparkling soda.
Garnish with a slice of pineapple or a sprig of mint for a decorative touch.
