There's a lot of nonsense online saying that fresh oysters can only be stored for a few hours, or up to a day. On the contrary, as any good purveyor will tell you, if you've bought very fresh ones that have been harvested right before sale — and you should — they'll keep for a week in a nice cold fridge. Fresh oysters will be tightly closed until you pry them open and will smell like the sea inside.u003cbr/u003e
