c rhubarb stalks
Rhubarb is very low in calories and a good source of dietary fiber, vitamin K, and calcium, though the oxalic acid content binds some minerals and limits bioavailability. It contains minimal sugar naturally and is particularly valued for its high pectin content, which facilitates gel formation in jams and preserves.
About
Rhubarb (Rheum rhabarbarum) is a perennial herbaceous plant native to Central Asia, cultivated for its tart, celery-like stalks (petioles) rather than its leaves, which are toxic due to high oxalic acid content. The edible stalks range in color from pale pink to deep crimson, with a crisp, fibrous texture and distinctly acidic flavor profile reminiscent of green apples with subtle floral notes. The plant thrives in cool climates and is botanically classified as a vegetable, though culinary tradition treats it as a fruit due to its use in sweet applications.
The most common commercial cultivar is 'Victoria,' characterized by thick red stalks and a tart flavor. 'Timperley Early' produces earlier in the season and is prized for forced rhubarb production. Other notable varieties include 'Champagne' and 'Turkish,' each with subtle flavor and color variations.
Culinary Uses
Rhubarb stalks are primarily used in sweet preparations, particularly jams, compotes, pies, and crumbles, where their natural tartness complements sugar and stone fruits like strawberries. They are stewed into sauces for desserts and breakfast dishes, or incorporated into cakes and quick breads for acidity and moisture. Less commonly, rhubarb appears in savory applications such as chutneys and glazes for game or pork, where its tartness cuts through rich flavors. The stalks require trimming and are frequently peeled before use to remove the tough outer fibers, then cut into segments and often pre-cooked to break down the cellular structure.
