This recipe actually started out as ice cubes for my son to chew on while teething, but I threw a few in my ice tea and it was great!
The extended simmering time for the rhubarb is crucial for developing flavor and achieving a thick paste; maintain a very low heat and stir frequently to prevent scorching, which can impart a bitter taste. For optimal flavor extraction and desired thickness, don't rush this process. Taste the rhubarb paste before freezing and adjust sweetness if desired, as rhubarb's tartness can vary. When making the tea, ensure the water is fully boiling to properly steep the tea bags, then allow adequate time for cooling and chilling for a refreshing drink. Consider adding a slice of fresh lemon or a sprig of mint when serving to enhance the overall aroma and presentation.
