How to choose geoduck

When choosing geoduck, look for specimens that are firm and heavy for their size, indicating freshness and quality. The shell should be clean and free of cracks or blemishes, as these can compromise the flavor and texture of the meat.

Avoid geoducks that have a strong, unpleasant odor, as this can be a sign of spoilage. Fresh geoduck should have a mild, briny scent reminiscent of the ocean, which is a good indicator of its quality. Additionally, ensure that the siphon is tightly closed; a gaping siphon can indicate that the geoduck is no longer fresh.

How to store geoduck

To ensure your geoduck remains fresh and safe to eat, store it in the refrigerator immediately after purchase. Keep it in a breathable container, such as a mesh bag or on a plate covered with a damp cloth, to maintain moisture while allowing airflow. The ideal storage temperature is between 32-40°F (0-4°C), which helps preserve its delicate texture and flavor.

Avoid storing geoduck in airtight containers, as this can lead to spoilage due to lack of oxygen. It's crucial to consume geoduck within 2-3 days of purchase for the best quality, as its freshness diminishes quickly. Additionally, refrain from freezing geoduck, as this can alter its texture and taste, making it less enjoyable when cooked.

✅ Extra Tip

To enhance the flavor and texture of geoduck, soak it in cold water with a bit of salt for about 30 minutes before cooking to help remove any grit and improve its natural sweetness.

How long does it last?

Geoducks, a type of large clam native to the Pacific Northwest, have a relatively short shelf life when not stored properly. Fresh geoducks can last for about 7-10 days in the refrigerator if kept in a breathable container, such as a mesh bag, and covered with a damp cloth to maintain moisture. If you choose to freeze geoducks, they can last for up to 6 months, but it's important to clean and properly seal them to prevent freezer burn. To ensure the best flavor and texture, it's recommended to consume geoducks as soon as possible after harvesting. Proper handling and storage are essential to enjoy their unique taste and culinary qualities.

What to do with leftovers?

Leftover geoduck can be a delightful addition to various dishes, ensuring that none of its unique flavor goes to waste. After enjoying it as sashimi or in a stir-fry, consider incorporating the remaining geoduck into a hearty seafood chowder or pasta dish. Its firm texture holds up well in soups, adding a touch of the ocean to your meal. You can also slice it thinly and toss it into a fresh salad for a satisfying crunch or use it to enhance a seafood risotto. If you have a significant amount left, try making a geoduck ceviche, marinating it in citrus juices for a refreshing appetizer. For longer storage, geoduck can be frozen; just be sure to slice it before freezing to make it easier to use in future recipes.
