**Tips for Choosing and Cleaning Clams**

Clams with sandy flesh or “full shells” are a common issue for many homemakers when preparing seafood. To avoid this, keep in mind the following tips for selecting and cleaning clams to ensure you end up with fresh and sand-free clams.

How to Choose Fresh Clams

When buying clams, select those with intact shells that are round and plump, and feel heavy for their size. Avoid clams with cracked or broken shells, those that feel light, or emit a foul odor, as these are likely to be old, have been stored for too long, or are dead. Such clams will not only taste bad but may also affect the quality of your dish.

Pay close attention to clams that are slightly open. They may be dead or past their prime. To ensure you’re choosing live clams, gently pry the shell open. If the clam quickly closes its shell, it’s a sign of a healthy clam. If there’s no reaction, the clam may be dead or too weak.

Tips for Cleaning Sand from Clams

Clams typically live in brackish water with a salinity of about 5%, so soaking them in regular tap water to get them to expel sand is usually ineffective. They will clamp shut and may die if soaked for too long in freshwater.

To effectively clean sand from clams, dissolve 1-2 tablespoons of salt in water, then add the clams. The familiar brackish environment will encourage the clams to open and expel sand. Soak the clams for about 2-3 hours to ensure they release all the sand.

If you want to speed up the cleaning process, you can add a few drops of cooking oil to the soaking water. The oil will float to the top, creating a barrier that prevents air from reaching the water, prompting the clams to open and expel sand more quickly.

Another tip to enhance effectiveness is to add a few slices of chili pepper to the soaking water. After about an hour, place the clams in a container, give them a good shake to “dizzy” them, then soak them again. In no time, they’ll open up and release all the sand.

Additionally, you can soak the clams in warm water at around 50°C. The warm water will stimulate the clams’ natural reflexes, causing them to absorb water as a self-preservation mechanism and simultaneously expel sand.

Another method for cleaning clams is to soak them in rice washing water. Rice washing water has a similar effect to saltwater, helping the clams expel sand efficiently. Soaking the clams in rice washing water for just 1-2 hours will give you clean clams ready for cooking.

With these tips, you’ll easily end up with fresh, crisp, and sweet clams without the sandy texture in every bite.

Frequently asked questions

First, you need to rinse the clams under cold running water to remove any sand or debris from the shells. Then, to ensure they are free of grit and to encourage them to spit out any sand inside, they need to be purged. This can be done by submerging them in a mixture of freshwater and salt, or corn flour and salt, for 20 minutes to an hour. Finally, give them a final rinse and scrub the shells to dislodge any remaining debris.

Purging is an essential step to ensure the clams are free of any grit or sand, which can ruin the texture and taste of your dish. It also encourages the clams to spit out any sand they may have inside, making them safer to eat.

One quick method is to soak the clams in a mixture of freshwater and 3% salt for 20 minutes, or in corn flour and salt water for an hour. Another technique is to place the clams in a single layer on a damp cloth in a cool place for a few hours, which will encourage them to spit out any sand. You can also tap each clam gently on a hard surface and then rinse them to help dislodge any remaining sand.

A clam that is safe to eat will have a slightly open shell, and when tapped, it will close tightly. If the shell does not close, or if it is broken, it is best to discard it. Also, check for any unusual odors – fresh clams should smell like the sea, and not fishy or foul.

It is best to cook clams as soon as possible after purchasing them, but if you need to store them, place them in a single layer on a damp cloth in the fridge. Cover them with a wet paper towel and then a layer of ice, and they should stay fresh for up to 2 days.
