Coffin Bay king oysters— about $900 per 1 kg (2.2 lbs)
It’s not for nothing that Coffin Bay oysters are called king. They have a really impressive size, the perfect texture, and a complex intense taste: both salty and sweet with a long-lasting salty aftertaste. In order to give gourmets a chance to extract an oyster 10 times bigger than a standard one, these mollusks are given the room to grow in the waters of Coffin Bay, off the coast of South Australia, for 6-7 years without hindrance.
My folks do multiple trips to Vic Market during their week-long stays in Melbourne for Coffin Bay Oysters. Only one stall sells them and they are huge.
i swear if you got dirt off the top of mount Everest (or told rich people that's wear you got it from) you could get them to eat it by telling them it has natural nutrients not found at ground level
