Summertime, and the living is easy. It will soon be too hot for oven time, so here is a nice cool option when you're sitting on your deck, listening to the waves, with a frosty libation in your hand!
There's the old adage about only eating oysters during the "R" months. Here is some info, courtesy of thespruceeats.com, which should ease any concerns:
Year-Round Oyster Enjoyment
Thanks to refrigeration, you can ignore the "r" rule and consume good oysters in spring and summer without incident. You can get them from cool waters or from farms, which gives them optimal flavor even in a month without an "r." In fact, a new genetic procedure being used by some commercial oyster farms renders farm-raised oysters sterile, so they don't spawn at all. These prime oysters are available for year-round enjoyment.
Best Oyster Season
The answer about oyster season depends on several factors. You have to know your oyster. If you feel confident that you are getting a fresh oyster from a cool-water location, you should have a tasty oyster that will not make you sick any time of year. Likewise, if you are in a state along the Gulf of Mexico, have no fear if you are barbecuing or whipping up some oysters Rockefeller.
Warm-weather bivalves pose no threat in that situation. When you're dining on local catch, though, it's best to note the weather. If that's the case, you may want to stick to the old "r" rule—better safe than sorry, right?
Buying and Storing Tips
If you have decided the time is right to buy some oysters, choose those that are heavy and full of water. They must be sold live, and live ones will be clamped shut or will clamp shut when they are tapped. A dead oyster will have a loose shell and should be avoided at all costs. Oysters taste the best when they are eaten within 24 hours of when you buy them, but you can store them in the refrigerator for up to five days in a mesh bag or open container covered with a damp cloth and large shell down.
I know folks who wolf down oysters until they are gone, usually as is, maybe with hot sauce or lemon juice. Mignonettes and some granitas add variety and some acidity to the rich salinity of the oyster.
