What specific culinary consideration often requires modification when preparing rhubarb stalks due to their inherent sourness?

The intense sourness almost always necessitates the addition of sugar

Rhubarb stalks are characterized by an intense inherent tartness or sourness. This strong flavor profile strongly dictates how the stalks are incorporated into recipes such as jams, crisps, or crumbles. In practice, this tartness almost invariably compels cooks to add substantial amounts of processed sugar to make the final product palatable for most consumers. Consequently, to preserve the maximum health advantages derived from the vegetable itself, it becomes critical to minimize this unnecessary intake of processed sugar, perhaps by employing natural sweetness alternatives like slow-cooking with low-glycemic fruits.
