The rhubarb plant belongs to the Polygonaceae family and grows best in cool climates with well-drained soil. While the stalks are edible and cherished, the leaves contain high levels of oxalic acid and are toxic if consumed. In Alberta, the plant thrives due to the province's cold winters and temperate summers, which provide the dormancy period rhubarb needs to flourish.
Rhubarb plants are typically divided and replanted every few years to maintain their vigor. They can be harvested from late spring to early summer. When mature, the stalks range from green to deep red, with the color often being an indicator of the variety rather than ripeness or sweetness.
Rhubarb has an extensive history dating back thousands of years, originally cultivated for medicinal purposes in Asia. Its journey to Europe involved trade routes and botanists, where it transitioned from a medicinal plant to a culinary ingredient. Rhubarb made its way to North America, including Canada, with European settlers.
In Alberta and the wider Canadian context, rhubarb found favor quickly. Its resilience in cooler climates and its unique taste made it popular among settlers and indigenous communities alike. Over the years, rhubarb became a staple in many Canadian gardens, and its tartness became synonymous with springtime desserts and preserves.
The tartness of rhubarb offers a delightful contrast in various dishes:
- Pies: Perhaps the most iconic is the rhubarb pie, often mixed with strawberries to balance its sourness.
- Jams and Preserves: Rhubarb jams, often combined with other fruits, offer a tangy spread for toast and pastries.
- Cakes and Muffins: Diced rhubarb can be added to baked goods, giving them a unique flavor.
- Sauces and Compotes: A rhubarb sauce can be drizzled over desserts or even savory dishes.
- Cocktails and Beverages: Rhubarb can be infused into drinks, offering a tart kick to cocktails and mocktails.
- Pickling: Pickled rhubarb can be a surprising and delightful accompaniment to various dishes.
- Stews: In some cultures, rhubarb is added to savory stews, where its acidity adds depth to the flavor profile.
When preparing rhubarb, it's essential to trim and discard the leaves. While the stalks might require some sugar or other sweeteners to counteract their sourness, their unique flavor ensures they remain a cherished ingredient in many kitchens, especially in Alberta.
