Prawns are a delicious addition to any seafood dish. To get the freshest prawns, make sure you pay attention to the packaging, the color, and the odor. When you clean your prawns, rinse them in cold water before you begin de-shelling and deveining. You'll need to remove the head, the tail, and the legs before cooking for most recipes.

Things You Should Know

  • Rinse the prawns thoroughly in cold water.
  • Remove the prawn's head and tail. Then, peel off the shell and legs.
  • Use a sharp knife to devein the prawn's body. Rinse again with cold water.

Rinsing and Storing Prawns

  1. If your prawns were frozen, you'll need to defrost them. Empty the prawns into a large bowl, preferably glass. Pour in some cold water and stir it around. Then drain the prawns and repeat this step several times. The entire process should take about fifteen minutes to fully defrost your prawns. [1]
    • Using the microwave to defrost prawns can make them soggy or overcooked.
  2. Watermark wikiHow to Clean Prawns
    Put the prawns in a colander and rinse them in the sink with cold water. Use your hands to rinse each prawn individually. As you are rinsing, keep an eye out for any spoiled prawns that are discolored or slimy. Prawns should appear white or gray before cooking. [2]
    • Never use water that is warmer than room temperature, as this could lead to soggy or rubbery prawns.

    Prawns should ideally be cooked immediately after cleaning. However, if you must store them for later, be sure to keep them in the refrigerator for no more than 24 hours. After this length of time, they may start to go bad.
    • For the freshest, best tasting prawns, consider cleaning and cooking them as soon as you get home from the store.
  4. Prawns need to be stored in a cool place like the refrigerator. They should be stored at a temperature between 32 °F (0 °C) and 38 °F (3 °C). Keep them together on a tray covered with plastic wrap or in a plastic container while they are in the fridge.
    • You can also freeze prawns for up to three months in your freezer at −18 °C (0 °F), but this may lead to less fresh tasting prawns.
    • Prawns should never be left out at room temperature for more than a few minutes.

Preparing the Body

  1. Watermark wikiHow to Clean Prawns
    Hold the prawn by the body with one hand and use your other hand to firmly grasp the prawn's head. Place the fingers from both hands at the intersection of the head and the body, where you want the break to occur. Pull back with both hands and twist until the head detaches. [3]
    • Discard the unused prawn heads in the trash immediately.
  2. Watermark wikiHow to Clean Prawns
    Hold the prawn by the body and grab the prawn tail with your other hand. Using a firm grip, pull the prawn tail off where it connects with the meaty part of the body. Throw away the tail once you remove it. [4]
    • Removing the tail before the rest of the shell will make the deshelling process much easier.
  3. Watermark wikiHow to Clean Prawns
    Once you have removed the shell, you should be able to peel off the remainder of the prawn's outer layer quite easily. Use your fingers to pull the legs off from its underside. Then peel back any remaining pieces of the shell. [5]
    • This should leave you with just the meaty part of prawn left.
  4. Use a sharp knife to cut a small line that runs down the length of the prawn's back. This should be done on the top of the prawn, the opposite side from where the legs were. Inside, you will see a small black line. Use the tip of the knife to pull out the vein and discard it. [6]
    • This black vein is the prawn's intestines. Removing it will help your prawns taste much better.
    • After deveining the prawns, you should rinse them once more with cold water. This will help ensure all remnants of the intestines are completely removed.

Choosing Good Prawns

  1. It may seem more convenient to choose prawns that have already been cooked or deshelled, but this will yield a great sacrifice in taste. Prawns taste best after the first time they are cooked, so it is important to purchase raw prawns.
    • Removing the shell gets rid of all the oils on the prawn, so choose prawns that have not been deshelled to help maintain the full flavor.
  2. Prawns should be purchased fresh and stored on a bed of ice in the meat section of your market or grocery store. This allows you to inspect them for discoloration and smell, and you will be able to choose the best ones. [7]
    • Buying prepackaged prawns means you will get prawns that are much older and will not taste nearly as good.
  3. Watermark wikiHow to Clean Prawns
    Prawns should be white or grayish in color with only white meat. Inspect each prawn for spots or areas of discoloration that indicate spoilage. Only choose prawns that are light in color and have no darker spots on them.
    • There are also brown varieties of prawns that should appear brown in color. These, too, should have no spots or discolored areas.
  4. While all seafood smells slightly fishy, prawns should not be too odorous. If there is a strong fishy smell to them, that means they are probably going bad. Choose prawns that smell fresh and clean, with only a hint of that seafood smell. [8]
    • This is another reason you should only purchase fresh prawns instead of prepackaged ones. If they are wrapped up in packing, you won't be able to check out how the prawns smell before you purchase them.

    There's no need for it, especially if they're going to be served full with the shells on, but I'm from Louisiana and we're not big on deveining shrimp here. That said, there's no harm in deveining them if you prefer it.
