Some who really love oyster believe that oysters have an intensity of flavour that is more like fruit and nuts than the animal flavour. And they also firmly spoke for that oyster should be chewed on, in order to feel the real flavour, salty and wet as a kiss!
And then there are those who become a little crazy and almost obsessed by the thought of oyster! They really connect oyster to glamour, luxury, real special occasions, preferably with good friends in a luxury environment.
Oysters have historic roots, already Neolithic man eat oysters on the Swedish west coast. Archaeologists have found lots of oyster shells buried in the kitchen waste from both the Neolithic and Bronze Age. Oysters are also said to have been popular among the Vikings and even famous personalities like Napoleon and Casanova is said to have been big consumers of oysters. Obsession with oysters also existed for 2 500 years ago when the Romans sent thousands of slaves to pick oysters at the English Channel.
There is hardly a more environmentally friendly fishing than oyster fishery. Current methods to fish oyster is to dive and pick oysters by hand or rake them up from a boat or pier. Oyster lives natural or is cultivated. When cultivated they grow on a pole, a raft, a rope or in a pool.
So, is oyster an aphrodisiac?
The common picture most of us have when oyster is used in romantic dinners is oysters served only with a few drops of lemon and a glass of champagne. Oysters it also considered as an strong aphrodisiac! And perhaps they can contribute to a sensual mood, but personally I think that the champagne will do more for sensuality. But as you can see further down in this article, oyster contains high amount of zinc, which plays an important role in reproduction in both men and women, and especially for sperm production. Maybe that has something to do with that oysters are considered as aphrodisiac!
Oyster (Ostreidae) is the name of different type of mollusc's that lives on sandy and rocky bottoms in shallow, salty and quite warm water. There are 50 known species of oysters in the world but the three most famous are the Crassostrea gigas (also called Japanese Oyster) Crassostrea virginica (Atlantic oysters that occurs along the U.S.east coast) and Ostrea edulis (European, plate, oysters). The European oyster (Ostrea Edulis) occurs from the Mediterranean in the south to Norway in the north. The European oyster has asymmetrical shell. One half is convex and the other is small and flat. They live from the water level down to 20 meters deep and feed on micro-plankton. Oysters are sessile filter feeders that filter microscopic organism and organic particles. Oyster switches sex several times during lifetime. Oysters are bisexual which means the same individual can reproduce as both male and female. When an oyster becomes sexually mature, at about the age of one year, it propagates itself as male. At the age of three, they may, if the water permits, first reproduce as female and then as a male again. Then it shifts between male and female for the rest of their lives. If the water temperature is to low (<16 degree Celsius) the oysters don’t have enough time to form mature eggs fast enough, and reproduction is in danger of failing. Cultured oysters may grow in water that is guaranteed above 16 degrees. They also have good access to custom feed.
Oyster thrives at the coasts, at river mouths and at places where freshwater meets saltwater.
