Mud crabs are undersea crustaceans that are native to Africa, Australia, and Asia and are known for their dark brown or black colored shells. Delicious when cooked, this delicacy can be caught near the shoreline or purchased at select fish markets. Before you boil the live crab, you should prepare it correctly so that it doesn’t suffer during the cooking process. Once you’re done chilling and washing it, you can either crack it into pieces or cook the mud crab whole.

  1. Find crabs that look healthy and that don’t have missing claws or legs. You’ll know the mud crab is alive and healthy if it moves its legs and claws when you touch it. Healthy adult mud crabs will be between 1.5–2 pounds (680–910 g). You can find live mud crabs at a fish market or in the seafood section of the grocery store. [1]
    • If the crab doesn’t move or react when you touch it, find another one that is more responsive.
    • Cooking dead crabs will result in a mushy and undesirable texture and could give you food poisoning.
  2. Grab the crab’s body from behind and leave the crab under the running faucet to remove any dirt that’s on its shell. Be careful when handling the mud crab so that it doesn’t pinch you with its claws. [2]
    • Mud crab claws are incredibly powerful and could cause serious injury.
    • Most stores will wrap rubber bands around the crab’s claws so that they can’t pinch you.
    • You can wear a pair of thick protective gloves to prevent injury.

  3. Line the bottom of the bowl with wet paper towels. Keeping the crab in a bowl will prevent it from moving around when you put it in the freezer. Crabs don't like the light, so you should place a towel over the bowl to prevent them from becoming agitated while you store them. [3]
    • You can keep a live mud crab for up to 24 hours out of the water before it dies.
  4. Placing the crab in the freezer will shock it and prevent it from suffering when you cook it. The crab shouldn’t move when you take it out of the freezer. [4]
    • Don’t leave the crab in the freezer too long or it will kill the crab and freeze the meat.
  5. Use a scissor to cut the bands or strings holding the crab’s claws shut so that you don’t boil them in the water with the crab. Discard the strings in the garbage and cook or clean the crab immediately. [5]
    • Don’t let the crab warm up or it will start moving around and suffer as you crack and clean it.

Cracking and Cleaning the Crab

  1. Boiling the individual pieces of the crab may be easier than boiling it whole because mud crabs are so large, which is why you may opt to take the crab apart before boiling it. The tail flap will be a V or U shaped flap on the bottom of the crab. Fit your fingers under the flap and pull up and twist to remove it. [6]
  2. Place your thumbs against the top shell and the crab's body. Pry off the top of the crab shell to remove it. This should reveal the inside of the crab’s body. [7]
    • Watch out for the sharp edges on the front of the crab’s shell.
  3. Hold the crab so that the underside is facing you. Pull and twist to remove the eyes of the crab. These pieces are not edible, so discard them after you remove them. [8]
  4. Run your fingers down each side to remove the phalanges on the inside of the crab’s body. These will look like fingers inside of the crab’s body. Remove both sets on each side of the crab’s body. [9]
    • The gills inside of the crab’s body are also not edible.
  5. Place the crab on a paper towel so that it doesn’t slip when you cut it. Center a kitchen knife on the body of the crab and apply downward pressure on the knife with your other hand to cut through the shell. [10]
    • Be careful when cutting through the crab so that you don’t cut yourself.
  6. Run the crabs body under cold water to clean out the gunk in the center of the crab. Some people like to eat the body of the crab while others prefer to discard it. [11]
  7. Use the knife to cut each arm at the joint closest to the body of the crab. You have now disassembled the crab and are ready to cook the individual pieces.

Boiling the Crab

  1. Use a pot that’s large enough to fit the crab. If you're cooking the crab whole, cook each crab individually. Don’t fill the pot all the way with water or it will overflow when you put the crab in it. [12]
    • If you put too much water in the pot, you can ladle the excess out.
  2. Season the water generously with salt and pepper and add 3 bay leaves to the water. This will impart more flavor into the crab. [13]
    • You can also add another seasoning to the water including paprika or garlic powder.
  3. Turn the stovetop to high and wait 10-15 minutes for bubbles to vigorously break the surface of the water. Then, turn the heat to medium-high so that the water is still boiling. [14]
  4. Use a pair of tongs to lower the crab or crab pieces into the water and place a lid over the pot. As the crab cooks, the shell should start to turn red. Don’t cook the crab for more than 12-15 minutes or the meat will get tough. [15]
  5. Fill a bowl up with cold water and ice cubes then place the cooked crab into the bowl. Plunging the crab in the ice water will stop the cooking process. [16]
  6. Either serve the crab immediately or store it in the refrigerator for 3-5 days. You can also freeze the crab for 3-5 months if you plan on eating it later. To eat the crab, crack the arms and claws with a shell food cracker and pull the meat out of the shell. [17]
    • You can dip the crab meat into melted butter as you eat it.

    Expert Answer
    While the term "crab guts" is often used to describe the internal organs of a crab, some people enjoy eating them. The yellowish substance known as "crab butter" or "tamale" is considered a delicacy and is essentially the hepatopancreas, which functions as the crab's liver and pancreas. It has a rich, savory flavor and is commonly consumed by those who appreciate its unique taste and texture. However, personal preferences vary, and not everyone may find this part of the crab appetizing.
