Types of Freshwater Clams

Not all freshwater clams are created equal. There are several types available in the market with varying flavors and sizes. Some popular ones include:

Asian Clams

These small-sized freshwater clams have a pinkish-yellow color with ridges across each shell. These shells do not easily open when cooked. The flesh has a crisp and crunchy texture.

Corbicula Fluminea

Also known as the golden clam or “golden river” clam because it can be found in most rivers worldwide. It has a yellowish-brown or green shell with visible grooves on its surface.

Eastern Floater

The eastern floater clam is usually found in rivers and streams across North America such as the Mississippi River basin, Mobile Bay Delta among others. This type of clam has an olive-green to brown shell color with faint wavy black lines on it.

Pilsbryoconcha Exilis

It is commonly referred to as the pea clam because of its size which is typically less than 3 mm wide making it hard to spot under rocks and sandbars.

Each type has unique attributes that make them excellent for specific dishes.

Buying Freshwater Clams

When buying freshwater clams, make sure they look clean and fresh before making your purchase. It’s essential to know where your clams come from and that the shellfish have been kept in cool, controlled environments that prevent contamination.

Look for freshwater clams in reputable fish markets, seafood departments of supermarkets or grocery stores. If buying in a supermarket or grocery store, check for freshness date on the pack if there is one.

Cleaning Freshwater Clams

Cleaning freshwater clams is a critical step in preparing them for cooking. To clean freshwater clams, follow these steps:

Soaking

In a large bowl or pot, cover the clams with water and salt them liberally 2-3 hours before cooking. This will induce spitting out sand and debris that they might have ingested while living at the bottom of lakes or rivers.

Scrubbing

Use a stiff-bristled brush to scrub off any dirt or debris on the shells.

Rinsing

Rinse well by placing them under running tap water till all dirt and debris has been washed from the surface.

Never cook freshwater clams that are open or broken as they are likely dead and could cause food poisoning.

Preparing Freshwater Clams for Cooking

Before starting to cook your seafood delicacy, checking your clam’s flesh is crucial to ensure that there isn’t any remaining sand or grit left inside it once you’re done cooking.

To remove sand and grit from clam meat, let the cleaned clams soak again (in clean salt water) within an hour before cooking again to make loosening any remaining bits of sand easier as they spit more grit out when placed back into clean water.

Cooking Methods for Freshwater Clams

There are three primary ways to cook freshwater clams: steaming, boiling, and grilling.

Q&A

Q1: What are freshwater clams and where can I find them?

Freshwater clams are bivalve mollusks that live in freshwater bodies like rivers, lakes, and ponds. They look similar to their saltwater counterparts but have thinner shells. You can find them in major grocery stores or fish markets.

Q2: How long should I soak the freshwater clams before cooking?

It is best to soak the freshwater clams for at least 30 minutes before cooking. This helps to remove any sand or debris that may be present inside. You can add cornmeal or flour to the water while soaking as this helps to stimulate the clam’s natural filtering process, which expels grit.

Q3: What is the best way to cook freshwater clams?

There are several ways you can cook freshwater clams. One of the most popular methods is steaming them with garlic, butter, white wine, and herbs. Another method is baking them with breadcrumbs, Parmesan cheese, parsley, and lemon zest. You can also sauté them until they open up and add them to pasta dishes.

Q4: How do you know when freshwater clams are cooked?

Freshwater clams are fully cooked when their shells open up wide enough for you to see the meat inside. Overcooking can make the flesh rubbery and tough while undercooking increases the risk of foodborne illness. Discard any unopened clam after cooking as they could be dead and potentially harmful if consumed.
