COOKING TIPS

In the kitchen.

1To serve raw, shuck carefully with an oyster knife, preserving the liquor, and serve immediately on ice with lemon wedges or mignonette sauce.
2Oysters cook very quickly. When grilling, broiling, or baking (e.g., Oysters Rockefeller), cook just until the edges begin to curl.
3For frying, coat shucked oysters in a seasoned cornmeal or flour mixture and fry for 1-2 minutes until golden brown and crisp.
4Add to soups and stews, like a classic oyster stew, during the final minutes of cooking to prevent them from becoming tough and rubbery.

STORAGE

Keep it fresh.

Store live oysters in the refrigerator (34-40°F or 1-4°C) with the cup-side down, covered with a damp cloth. Do not store in a sealed container or water.
Consume fresh, live oysters within 1-2 days of purchase for optimal safety and flavor. Discard any with open shells that do not close when tapped.
Shucked oysters should be refrigerated in a sealed container with their liquor and consumed within 3 days.

FAQ

Are rock oysters keto-friendly?

Rock oysters are generally considered keto-friendly. While they contain a small amount of carbohydrates (roughly 5g per 100g), they can easily fit into a low-carb or ketogenic diet when consumed in standard serving sizes.

Are rock oysters gluten-free?

Naturally, rock oysters are 100% gluten-free. However, if you are eating them at a restaurant, ensure they aren't served with crackers, breading, or sauces that may contain wheat-based thickeners.

How do you eat rock oysters?

Rock oysters are most commonly served raw on the half-shell with simple accompaniments like lemon juice, mignonette sauce, or a dash of hot sauce. They can also be grilled, steamed, or baked in dishes like Oysters Rockefeller.

What do rock oysters taste like?

Rock oysters typically have a salty, briny flavor with a firm, creamy texture. Depending on their origin, they may also exhibit sweet, mineral, or metallic undertones compared to other oyster varieties.

How can you tell if a rock oyster is fresh?

A fresh, live oyster should have a tightly closed shell; if the shell is slightly open, it should snap shut when tapped. When opened, it should smell like the fresh ocean and be plump and glistening in its own clear liquid.

How should you store fresh rock oysters?

Store live rock oysters in the refrigerator at 4-5°C (40°F) in an open container covered with a damp cloth to keep them moist. Never store them in an airtight bag or in fresh water, as this will kill the oysters.

Can you eat rock oysters raw?

Yes, rock oysters are frequently enjoyed raw. However, to minimize the risk of foodborne illness, ensure they are sourced from reputable suppliers and kept at the correct temperature. Vulnerable groups, such as pregnant women, should only eat them fully cooked.
