Cocktail hour - what’s on our minds
Rhubarb Quoogles:
“Rhubarb is a vegetable” we all know this is a lie… vegetables aren’t a thing
Part of the buckwheat family and also related to swiss chard
Grown primarily these days as a food crop, it has thousands of years of history as a medicine.
The origins are not precisely known. Although it is thought that it made its way more widely into Europe via the silk road during around the 14th century through Aleppo and Smyrna. It was referred to as “Turkish Rhubarb”
During the medieval age in Europe it was more expensive than Cinnamon, opium and saffron.
Rhubarb was harvested in Scotland from at least 1786, having been introduced to the Botanical Garden in Edinburgh by the traveller Bruce of Kinnaird in 1774. He brought the seeds from Abyssinia and they produced 3000 plants.
There is now a region in Yorkshire England called the Rhubarb Triangle which is famous for it’s forced rhubarb. There used to be many producers but the number has dwindled down to just 11 since the rhubarb boom peaked during the world wars.
“Forced” Rhubarb is grown in dark sheds that are still only lit by candle light. This makes the rhubarb considerably sweeter. The plants are grown outside and allowed to experience a frost
The coolest thing is that when rhubarb is growing at its fastest in those darkened sheds you can actually hear the cracking and popping of the stems growing.
There is a lot of variation in color. I’ve only been able to grow a green/red variety. I REALLY REALLY want a variety with fully red stems, but I seem to be shitty at growing them.
Rhubarb is grown for its petioles (AKA the stalks) Which is the part of the plant that attaches the leaves to the stems, So the “stem” of rhubarb are actually underground. Usually referred to as “Crowns”
