In the Patch –Rhubarb Patch
My first encounter with fresh rhubarb was a frightening experience for me. I was about six years old and my aunt had baked a strawberry rhubarb pie. It was a slice of heaven, lightly heated with a scoop of vanilla ice cream. The next day one of my older cousins pointed out the rhubarb plant to me in the garden and suggested that I try it fresh seeing as I had enjoyed the pie so much. I eagerly broke off a stalk and started munching away. I quickly fled to the safety of my aunt’s kitchen with tears in my eyes making gagging accusations that my cousin was trying to poison me. It took about ten years for me to get over that experience before I started to eat and cook rhubarb again.
There is often discussion surrounding rhubarb that the leaves contain poisonous compounds. The most dangerous substance found in the leaves is oxalic acid. The median lethal dose for pure oxalic acid is about one ounce for a 150 lb person. The oxalic acid content found in rhubarb leaves vary but it would require that same 150 lb person to consume around 12 pounds of the extremely sour leaves in one sitting to cause death.
Rhubarb is indigenous to the Gobi region of eastern Asia and it is believed that the Hun’s and Mongol’s brought the plant westward with them. Rhubarb has been used throughout history as a medicinal plant in traditional Chinese medicine for its strong laxative properties and for its astringent effect on the mucous membranes of the mouth and the nasal cavity.
The consumption of rhubarb as a food became commonplace when the price of sugar fell in the late 1700’s and became available to the common people of England. Rhubarb eventually found its way to North America in the early 1800’s.
Although we cook rhubarb like a fruit it is an herbaceous perennial that is classified as a vegetable. In Iran and Afghanistan it is commonly cooked with spinach in a preparation known as khorest which is similar to stew. Polish peoples boil rhubarb with potatoes and aromatics while Italians use rhubarb to make a mildly alcoholic beverage called rabarbaro touted as a health tonic.
I enjoy rhubarb in a number of ways and prefer to incorporate it with citrus fruits and ginger. Try this traditional British recipe for Rhubarb and Ginger Jam. I recommend serving it with fresh warm scones at breakfast or serve it at dinner paired with roasted pork loin.
Rhubarb and Ginger Jam
Ingredients:
Two lb rhubarb
Two lb sugar
two cups of water
Four oz crystallized (candied) Ginger
One oz fresh ginger root
Zest of one lemon
Juice of two fresh Lemons
One Jalapeno or Habanero pepper seeded and finely chopped- optional for those who like it hot!
Method: Wash and trim the rhubarb and cut it into one inch lengths. Squeeze the ginger in a garlic press to extract its juice and reserve. Chop the candied ginger into small pieces.
In a heavy bottomed saucepan combine the rhubarb, sugar, water, lemon zest and juice.
Over medium high heat bring the mixture to a gentle boil. Allow the mixture to boil for 15-20 minutes stirring occasionally.
Add the candied ginger and reduce heat to medium. Allow the mixture to simmer for a further 15-20 minutes. Skim the surface with a sieve to remove any bubbles and scum. Pour the jam into sterilized jars to be sealed and cooled.
The Ancient Greeks referred to rhubarb as “the vegetable of barbarians” and understandably so with its blood red, celery like stalks and its strong astringent flavour peppered with the toxic oxalic acid which can make you feel like your mouth has been pulled inside out when eaten raw.
The name rhubarb is Greek in origin and combined two words; rha and barbarum. Rha refers to the plant and to the Volga River where along its banks rhubarb has grown wild for centuries. It also symbolized the laxative effects of rhubarb and how it could medicinally be used to make your bowels evacuate themselves and flow like the Volga River.
Originally cultivated in China for its medicinal qualities; rhubarb became so valued that the Qing Dynasty on a number of occasions decreed that no tea or rhubarb was to be exported as foreign barbarians would surely die without these necessary staples.
It wasn’t until the 1700’s when sugar prices fell that we saw rhubarb being consumed as a food and cultivated in most people’s gardens. Since its arrival in North America rhubarb has found its home and is used in a variety of preparations that includes breads, cakes, pies, tarts and jams.
Whether you get your rhubarb from your back yard, a neighbor or the grocery store you need to know about the two basic types of rhubarb available and their differences. The traditional variety displays thick green stalks that possess a balanced mellow flavor while the modern hothouse variety has slender stalks with a deep red color which lends itself to striking presentation it is also far bitterer.
After you have selected your rhubarb you will need to rinse the stalks of any dirt and trim away the leaves as the leaves contain poisonous compounds. The most potent of which is oxalic acid. The median lethal dose for pure oxalic acid is about one ounce for a 150 lb. person. The oxalic acid content found in rhubarb leaves vary but it would require that same 150 lb. person to consume around 12 pounds of the awfully sour leaves in one sitting to cause death. Although tempting, do not peel the fibrous skin from the stalks as it holds most of the color and flavor.
If you do not plan on immediately using your rhubarb it can be stored safely for up to a week sealed in a plastic bag in the refrigerator. Alternately you may choose to freeze or can your rhubarb for longer storage. When rhubarb is cooked its juices will naturally thicken and the fibers will fray making it perfect to use for jams and chutneys.
