Oysters have provided humanity with fresh and nutritious protein for thousands of years. Whether serving in a stew or raw on the half shell, always get them from pristine waters and a reliable purveyor. Apparently they are growing here in Brooklyn once again, but I won’t be eating those anytime soon. Remember, no matter where they are from, they are highly perishable. Keep them cool, moist and store according to instructions. Discard any suspicious ones (opened) immediately.
