Are they a fruit or a vegetable?
Are they sweet or savory?
The answer, surprisingly, is yes to all of the above. Depending on whom you ask, rhubarb can be classified as fruit or vegetable. It can be prepared with sugar for jams and pies, and its sourness makes it ideal for pickling. Rhubarb is a good source of potassium, vitamin C, and dietary fiber, and it is extremely low in calories.
How to choose them
Size doesn't matter when choosing rhubarb. Look for red stalks that are flat and firm, not curled or limp. Peak season spans April through June.
How to use them
Rhubarb stalks are quite tart, so they are commonly cooked with sugar or other sweeteners. Check out this recipe for strawberry-rhubarb pie, a popular dessert in spring and summer. To enjoy rhubarb all year long, try pickling it or making rhubarb jam. If canned properly, both of these preparations can be stored for months before they're eaten.
How to store them
Wrap rhubarb plants in plastic and store them in the fridge for up to one week.
