First and foremost, it is essential to handle live blue crabs carefully. They have sharp claws and can give a painful pinch, so it is to wear gloves or use tongs for your safety. Keep in mind that crabs are best when cooked alive, as their meat quickly deteriorates after they die. Also, consider using a large container to hold the crabs while you clean them.
Begin by holding the crab firmly by the back shell, or carapace, with one hand, making sure to keep your fingers away from the claws. With the other hand, gently pull off the top shell. This will reveal the crab’s internal organs, including the lungs, known as the “deadman” or gills. These should be removed as they can negatively affect the flavor of the crab.
Next, remove the crab’s mandibles, or mouthparts, which are located on either side of the crab’s face. They can be easily pulled off with your fingers or cut off with a knife. This step is not mandatory, but it can help improve the overall presentation of the crab.
After removing the deadman and mandibles, focus on the main body of the crab. It is important to remove the apron, which is the triangular shaped flap located on the bottom of the crab. Gently lift it up and snap it off at the base, discarding it once removed.
Now, it’s time to clean the crab’s body cavity. Rinse it under cold running water, making sure to remove any remaining bits of the deadman and other internal organs. This step is crucial to ensure the freshness and flavor of the crabmeat.
Once the body cavity is clean, break the crab in half by placing your thumbs under the crab’s body on each side and pulling it apart. This will expose the crab’s meaty sections, or clusters. Rinse each cluster under cold running water to remove any debris or excess fluids.
At this point, you can choose to keep the clusters intact or break them into smaller pieces for easier consumption. To do this, use a knife or kitchen shears to cut the clusters into halves or thirds, depending on your desired size.
Finally, fill a large bowl or sink with cold water and add some salt or vinegar. This step is known as “purging” and helps to remove any remaining dirt or impurities from the crab. Let the crab pieces soak in the solution for approximately 10-15 minutes, then rinse them under cold running water once again.
Congratulations, you have successfully cleaned blue crabs! You can now proceed to cook them using your favorite recipe. Whether you steam, boil, or grill them, the clean and fresh blue crabmeat will surely make for a delightful meal.
Remember, practicing proper cleaning techniques is crucial not only for the taste and quality of the crabmeat but also for your health and safety. So, take your time, follow the steps mentioned above, and enjoy the deliciousness that blue crabs have to offer!
