When I was younger there was no way I would eat oysters raw, cooked, or in a shot! But now days I love them. I don’t know if there’s any truth to this but I’ve alway heard oysters are best eaten in months that end in “R”.
Actually that's months that contain the letter "R".
That would add January, February, March and April to the list.
It has to do with the water temps and the breeding cycle.
Oysters eaten at the wrong time can be slimy(er) and mushy.
Very unappealing.
Also in the old days before reefer cars they were tough to transport in warmer months.
