My grandpa in Toronto can't find live oysters that:
are free of worms and parasites.
can be easily bought from an ubiquitous supermarket like Loblaws, T & T, Whole Foods. He always returns home within 2 hours after his shopping to keep his food fresh. He doesn't live near specialty seafood stores, like Diana's Seafood, Honest Weight.
Whenever he follows this video, these instructions or Jamie Oliver's to steam Crassostrea virginica bought at Loblaws (like those branded Malpeque or Raspberry Point) , the meat shrinks to the size of a teaspoon. Thus what's he flubbing? What must he correct?
