Soaking the Clams

  1. You can use saltwater or freshwater. Soaking methods differ depending on which type of water you choose. Saltwater is often considered to be the more effective method as it mimics the clams’ natural habitat for cleaning.
    • To soak the clams in saltwater, mix 1/3-cup salt (100 grams) with 1 gallon (3.8 liters) of water. Soak the clams for 30 minutes. Take the clams out by hand. Make another bowl of the saltwater mixture and soak the clams again. This process should be repeated 1-2 more times. [4]
    • For freshwater, submerge the clams in a bowl of cool water. It is fine to use tap water. Let the clams soak for 20 minutes to an hour. The clams will purge any salt, sand, or other grit naturally during this time. [5]
  2. This may help clean the grit from the clams while they are soaking. The cornmeal may alter the taste of the clams by making them slightly sweeter. [6]

  • Question
    How can I tell if my clams are edible?
    Community Answer
    When you rinse them in cold water, they should close. It they don't close, it means they are dead and must be disposed of. When you cook them, they will open up again. If they are not open when cooked, throw them away. Don't try to open them, it means they are not edible.

  • Question
    Is there an efficient way to clean a large number of clams?
    Community Answer
    If you have them alive, you can put them in fresh, clean water that's pretty cold for about 30 minutes. When they breath, the live clams will filter out sand and salt water out of their systems. You can put multiple clams in a bucket of water to do this. However, if you are cleaning their shells, you have to scrub each one individually.

      Warnings

      • Do not eat a clam that is still closed after it has been cooked. The clam may be dead and infected with bacteria. Avoid the risk of food poisoning and discard these clams.
      • You should always cook clams immediately after you clean them to avoid any potential health risks.
