If the shell does not close tightly or the oyster meat is dry when the shell is open, the product should be discarded. Avoid eating oysters when their shell is broken or damaged.
If there are large cracks or broken or damaged areas, throw the oyster away. There should be no gaps within the shell. If the shell is also open, the oyster is bad. Oyster shells are glossy white in color with pink and gray streaks, if yours looks greenish or brown, you should discard the oyster.
Once opened, oysters will keep for up to 7 days in the fridge, but be aware: they will absorb any strong flavours (for example rock melon and onion tend to taint the flavour, no matter how well packed your oysters are).
You'll want to serve oysters as soon after shucking them as possible. You can keep them cold by setting them on a tray of crushed ice. Serve them plain or with a simple squirt of lemon juice.
If the shell remains shut after cooking, he says, “the muscle that holds the shell together is working. It's alive. Or if an oyster, clam or mussel doesn't open when it's cooked, sometimes it's dead — killed in the cooking process — but the muscle is just so joined to the shell that it's not letting go.”
One way to store the oysters is on a bed of ice. Lay the oysters with the deep side down on the ice and make sure the ice doesn't melt. Oysters stored this way will last about two days.
We're often asked, “Are you supposed to chew oysters?” and we're here to tell you that despite what you may have heard, it's not recommended to swallow an oyster whole. Biting into the oyster allows flavorful juices to escape and enhances the overall savoring experience.
Before you're ready to eat, let your oysters sit in a small bowl of icy water for 10 or so minutes. You'll notice sand and other debris will fall to the bottom of the water. Remove the oysters and discard the water. With a hard bristled brush, scrub the outside of the oyster.
"Always begin by loosening the oyster. Generally, there is a small fork provided for this purpose, so that it is not attached to the shell. Then, bring the oyster shell to the lip of your mouth, tip slightly, and enjoy."
Whether you buy oysters from a fish market or from a grocery store, you'll have to clean them before you prepare or cook them. Oysters live in the ocean, where they collect dirt and debris on their shells. To make them fit for consumption, this dirt must be scrubbed from the outside of the shell.
Kept at a proper temperature and prevented from drying out, an oyster can live in your fridge for up to a month, or even a little longerHowever, understand that the longer your oysters are out of the water, the more likely you are to lose a few. Always check to make sure the oysters are closed before you eat them.
Rule of thumb is at least 4,000 years old. Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning.
Storing Oysters
You can refrigerate freshly-shelled oysters in their own liquor (the liquid they sit in) for two days, but use them as quickly as you can. You can freeze shucked oysters but never freeze oysters in their shells. Frozen raw shucked oysters will keep for up to three months.
Potentially life-threatening to most people, symptoms of Vibrio vulnificus infection occurs within 24 to 48 hours of ingestion and may include symptoms such as sudden chills, fever, nausea, vomiting, diarrhea, shock and skin lesions.
Cover the oysters with a damp paper towel or damp cloth and place them in the fridge. They should keep for up to seven days like this, but it's best to eat them within a day or two.
Because oysters feed by filtering water, bacteria can concentrate in their tissues. When someone eats raw or undercooked oysters, viruses or bacteria that may be in the oyster can cause illness. You can get very sick from eating raw oysters. Most Vibrio infections from oysters result in only diarrhea and vomiting.
Eating raw or undercooked shellfish, like raw oysters contaminated with Vibrio, may cause foodborne illness (nausea, vomiting and diarrhea). Cooking oysters to an internal temperature of 74⁰C is the safest way to serve them. 1. Obtain oysters from approved suppliers only.
Oysters: Appetizer Engagements: 3-4 oysters per person. As a second or third course (where other items are being served with the oysters): 5-6 oysters per person. For a main course (including an Oyster Roast or a Bull & Oyster Roast), figure 6-8 oysters per person. Clams: Many people serve clams along with oysters.
What makes oysters so special to many people is how distinctively they taste and smell like the ocean. When they're eaten raw, it's almost like taking a straight shot of the sea. Now if you dislike the ocean and are not a fan of seafood, then oysters will most likely never be the delicacy for you.
Shucked oysters will have a good-through date. If they go past this date, you'll want to discard them. Shucked oysters typically have a 10-14 day refrigerated shelf life upon receipt.
To clean, place oysters in a colander in a sink and rinse under cold running water. If you can, cover them with crushed ice while shaking them under the running water. This will keep them colder and the ice will help clean away any dirt. If necessary, scrub off any mud and debris with a scrub brush.
Look for the telltale milky sac that indicates an oyster is spawning. If it's just getting going, the sac is little more than a thin, cream-colored line less than half an inch long. If the oyster is in high gear, the sac will be large and cloudy, overtaking much of the oyster's body mass.
Oyster liquor is the natural juice that you find inside of raw oysters. This liquor is very important as it keeps the oyster alive when it's out of the water. Don't rinse or dump the liquor out though before you eat it—it is what keeps those oysters fresh.
Oysters are a rich source of vitamin D, copper, zinc, and manganese. These micronutrients, in combination with calcium, are thought to be key to slowing or even preventing bone loss in older women due to osteoporosis. Additionally, dietary sources of these minerals are thought to be more effective than supplements.
