Salty Oysters on the Half-shell Four Ways

It used to be that Southerners ate oysters only in months with the letter r in them because it was just too hot from May to August to ensure their safety and freshness. Today, thanks to the wonders of modern refrigeration, they can be eaten year-round. Keep in mind that oysters must be cooked or eaten alive, so freshness is paramount when using oysters, mussels, clams, and scallops. Fresh, properly stored oysters should smell clean and briny, with no hint of fishiness. Any that remain open when tapped prior to cooking or closed after cooking should be discarded.
