What is Rhubarb? A brief history

Rhubarb is famous for its use in pies. It is no wonder it is also known as the pie plant.

Scientifically known as rheum rhabarbarum, this plant is believed to have originated in Asia, although the exact region remains a mystery. Nowadays, rhubarb thrives in cool, temperate climates around the world.

Unlike most plants that are entirely edible, the enormous leaves are not edible. They contain oxalic acid, hence are considered toxic. Only the ruby-colored stalks are consumed.

In Asian culture, rhubarb roots are an integral medicinal components. Since antiquity they were used for cleansing and purification.

Storing vegetables appears simple. However, it may prove unsuccessful if you are not aware of how each vegetable is structured. Fresh rhubarb stalks become limp fairly quickly. The shelf life thus depends on how you store and handle them.

Here is how long it lasts when raw, cooked or preserved.

Shelf life of fresh rhubarb (in the fridge)

Rhubarb has ethylene, which hastens ripeness. As such, when refrigerating, avoid placing them near other fruits and vegetables.

In addition, the best way to store them is to loosely wrap the stalks in either foil or plastic wrap.

Avoid cramping them tightly in airtight bags. Cramping the stalks prevents ethylene from escaping, hence causes them to soften and become limp.

Moreover, you can freshen the stalks by placing in water, after a few days.

When well refrigerated, these stalks keep well for 2-3 weeks.

  2. Blanch the pieces for 3 minutes in boiling water. Dip in icy water and pat dry. Pack the pieces into Ziploc bags and freeze.
  3. Pack the raw pieces in sugar syrup. This is important in preserving color, flavor and structure. Mix the pieces and syrup well before storing in bags.
  4. Use dry sugar pack. This entails coating the pieces in sugar, before freezing. It works the same as sugar syrup.
