How to choose crabs

When choosing crabs, they should be alive and active if bought fresh. Their shells should be intact and not feel light, which can indicate a lack of meat inside. Observe the movement of the crabs; they should be lively, not lethargic.

Avoid crabs that have cracked shells or any foul odor. Fresh crabs should have a mild, briny scent, not an overpowering fishy smell.

How to store crabs

Live crabs should be kept in a cool, moist environment like the refrigerator and should be consumed within 1-2 days. Store them in a container that allows for ventilation to ensure they can breathe. If you need to store them for a longer period, freezing cooked crabs is advisable, as they can last up to 2-3 months when properly packaged.

Placing live crabs in water can lead to suffocation and spoilage. It’s crucial to maintain a cool and moist environment without submerging them. Handle them gently to prevent any damage and to keep them fresh.

✅ Extra Tip

To keep live crabs moist without submerging them, cover them with a damp cloth in the refrigerator. This provides the necessary moisture while allowing them to breathe.

How long do they last?

Crabs can last for 1-2 days in the refrigerator when stored in an airtight container. For longer storage, crabs can be frozen for up to 2-3 months. Proper packaging, such as vacuum-sealing, helps maintain their quality over longer storage periods.

What to do with leftovers?

Leftover crabs can be used in a variety of seafood dishes. Flake the meat and add it to salads with greens, avocado, and a citrus vinaigrette, or mix it into a pasta dish with a creamy sauce. Crab meat is also great in crab cakes, where it can be combined with breadcrumbs, eggs, and seasonings, then fried until golden.

Use crab meat in a seafood stew or chowder, where its sweet, delicate flavor enhances the dish. If you have a lot of crab meat, consider making a batch of crab dip with cream cheese, herbs, and lemon juice, perfect for serving with crackers or bread. Crab meat can also be used as a topping for pizzas or flatbreads, paired with ingredients like cream cheese, capers, and dill. For a quick and elegant appetizer, serve crab meat with a drizzle of lemon butter or toss it into a seafood risotto for a luxurious meal.
