How to choose raw oysters

There are a couple of things to be mindful of when picking raw oysters:

Get your oysters from somewhere you trust, no matter if that’s your local grocer or a fishmonger.
Look for signs of freshness: if it doesn’t look or smell right, be cautious.
Ask when they were harvested and how long you can safely store them. Some oysters will come with a tag that indicates this information. Consider hanging onto this tag for reference.
Make sure you pick up your oysters last on your shopping or to-do list and keep them cold and alive while you transport them home. Most fishmongers will offer you a bag of ice to put with the oysters to keep them chilled.
Once you have them home, put the oysters on a baking sheet between two damp towels in the refrigerator.

Quick tip

Fresh water is a no-no for oysters. Make sure your oysters haven’t been sitting in water before purchasing, and don’t put them on ice before shucking and serving, as the melted fresh water is not good for them.

How to shuck an oyster

If you’ve ever watched any cooking show, you’ll know that shucking oysters is a real test. So don’t worry if you don’t get this on the first attempt. With some practice and following these steps, you’ll get the hang of it!

Shucking the oysters : Hold an oyster, flat-side up, with a kitchen towel. Make sure to leave the end (hinged side) exposed. Place the tip of the oyster shucker between the two shells right where they hinge together. Press inward with firm pressure, wiggling your shucker a little, until it pops open. Keep the oyster level so that the liquid stays inside.
Clean your oyster shucker : You don’t want bits of shell in your oyster!
Open the oyster shell : Use the shucker or oyster knife to insert it into the shell and twist gently. You may need to do this at a few spots. Once the shell has been released, run the shucker along the inner upper shell to release the muscle that attaches there.
Detach the oyster from the shell : Remove the top shell completely, and then run your shucker under the oyster to detach it from the shell.
Place on ice and serve: Place the oyster on top of ice with the narrow end facing inward. Repeat until all the oysters are shucked, and then serve right away.

How to serve oysters on the half shell

Here are some idea of how to serve oysters on the half shell:

Serving tray : Raw oysters are typically served on a metal tray since it keeps things cold. If you don’t have metal, opt for ceramic.
Garnishes : For the classic, purist approach, you can serve with lemon wedges to add a squeeze of bright, fresh citrus. This will balance some of the salty flavor from the oysters. Alternatively, you can add fresh herbs, ginger, chili flakes, or lime juice – it all depends on the flavor you want to offer or the style of oysters you’re intending to serve.
Sauce : You can offer hot sauce, like Tabasco. You can also include a classic French mignonette which has vinegar, minced shallots, and pepper. Or try this champagne mignonette for a delicious twist! Adding sauces as options leaves it up to your guests to decide how much of the briny oyster they want to taste or disguise.

How to eat oysters on the half shell

Yes, you really do slurp them! Oysters on the half shell have the muscle (edible part) detached, so as you tilt your head back, it should slide into your mouth. If it isn’t completely detached, you can use your fork to gently move it around and detach it. You can chew it a couple of times before swallowing, or some people swallow it down the hatch immediately.

What to do with leftover shucked oysters

In the unlikely event that you have leftovers, you can store them in a covered container in your fridge for up to 3 days, but it’s not wise to eat them raw after that. But they are delicious topped with a little garlic butter, chopped spinach, and breadcrumbs, and baked as Oysters Rockefeller.
