Rhubarb
Description
Rhubarb is a perennial plant known for its tart-flavored stalks, which are commonly used in culinary applications. Often considered a vegetable, it is typically treated as a fruit in the kitchen, especially in desserts. The petioles (stalks) are the only edible part of the plant, as the leaves contain oxalic acid and are toxic if consumed. Rhubarb stalks range in color from green to deep red and have a crisp texture similar to celery, with a much more tart flavor.
Common uses
Rhubarb is most commonly used in sweet applications, often paired with strawberries or apples to balance its tartness. It's also used in savory dishes, where it can add a pleasant acidity.
