Oysters

One dozen fresh Spencer Gulf oysters - picked 'em up at the Caltex Servo in Cowell, on the Eyre Peninsula. MDR remembered to pack his oyster shucker this trip.
MB was intrigued to learn that Cowell is also home to a Jade deposit, so she bought herself a jade pendant at the Jade Motel.
From SMH 08 Feb 2004 - Cowell Jade Factory
"The history of jade in the Cowell area is a recent development. In 1965, Harry Schiller, a local farmer first discovered significant deposits of nephrite jade near Cowell. The next decade saw little real development and it wasn't until 1974, when the South Australian government became involved, that the potential of the area was realised. A geological assessment found a total of 91 separate jade outcrops (this has subsequently been increased to 115) in a small 10 sq km area which is now known as the Cowell Jade Province. The deposit is recognised as containing about 80 000 tonnes which means that it represents about 90 per cent of the world's known jade reserves (this excludes China for which figures are not available). In the decade to 1987 over 1500 tonnes of jade had been extracted of which 40 per cent was either dark green or black. Cowell jade is now exported to countries as diverse as India, West Germany, USA, Japan, Canada, Hong Kong, Taiwan, Italy and New Zealand."
