🐚 Types of Clams – A Detailed Guide

Clams come in many shapes, sizes, and flavors. Some are ideal for raw consumption, while others are best enjoyed cooked. Here’s everything you need to know about the most popular types:

Littleneck Clams

Littlenecks are the smallest of hard-shell clams, usually 1–2 inches across. Their shells are smooth, firm, and tightly closed, often with subtle ridges and natural color patterns of beige, gray, or brown. The meat inside is tender, juicy, and slightly sweet, with a fresh ocean taste.

Habitat:

• Found in sandy or muddy tidal flats along the Atlantic coast, particularly in New England.

Nutritional Notes:

• High in protein (~12g per 100g), low in fat (~1g), rich in iron and vitamin B12.

Culinary Uses:

• Raw: Excellent on the half-shell with lemon or mignonette sauce.

• Cooked: Lightly steamed, added to pasta, chowders, or stir-fries.

Preparation Tips:

• Scrub shells thoroughly.

• Check that the clam closes when tapped; discard any that remain open.

• Serve immediately if eating raw.

Fun Fact: Littlenecks are considered the most tender and sweet of all hard-shell clams, making them a favorite for raw bar enthusiasts.

Cherrystone Clams

Cherrystone clams are larger than littlenecks, about 2–3 inches in diameter. Their shells are thick and sturdy, with a slightly rugged texture. The meat is firmer and slightly chewier than littlenecks, with a mild, slightly salty flavor.

Habitat:

• Commonly harvested along the Atlantic coast of the US, thriving in sandy and muddy bays.

Nutritional Notes:

• High in protein, iron, and vitamin B12. Slightly higher in calories than littlenecks due to larger size.

Culinary Uses:

• Raw: Can be eaten on the half-shell if very fresh.

• Cooked: Steamed, baked, or stuffed; popular in clam bakes and chowders.

Preparation Tips:

• Soak in cold water for 20–30 minutes to remove sand before cooking.

• Steam until shells open (usually 5–7 minutes).

Fun Fact: Cherrystones are often the choice for classic New England clam bakes because their firmer texture holds up well in long cooking.

Manila Clams

Small and oval-shaped, usually 1–2 inches, with colorful striations on the shell (brown, cream, or orange patterns). The meat is tender, sweet, and slightly nutty in flavor.

Habitat:

• Native to Asia but widely farmed on both coasts of the US and Europe.

• Found in sandy tidal areas and estuaries.

Nutritional Notes:

• High in lean protein and vitamin B12, low fat, moderate sodium naturally from the sea.

Culinary Uses:

• Raw: Sushi, sashimi, or ceviche when very fresh.

• Cooked: Excellent in clear soups, seafood stews, pasta, and stir-fries.

Preparation Tips:

• Rinse thoroughly to remove sand.

• Check liveliness before consuming raw.

• Steam or boil briefly to maintain tenderness.

Fun Fact: Manila clams are prized in Japanese cuisine for their delicate flavor and subtle sweetness.

Soft-Shell Clams (Steamers)

Longer, oval, soft shells that are slightly brittle. Meat is chewier and sweeter than hard-shell clams, with a pronounced ocean flavor. They often have a siphon (“neck”) extending from the shell.

Habitat:

• Atlantic coast in sandy mudflats.

Nutritional Notes:

• Rich in protein, low fat, a good source of iron and vitamin B12.

Culinary Uses:

• Rarely eaten raw due to delicate shells.

• Popular fried (New England-style clam strips), steamed, or in chowders.

Preparation Tips:

• Scrub shells and soak in cold water to purge sand.

• Steam or fry until cooked through.

Fun Fact: Soft-shell clams are often “raked” rather than dug, making them a specialty for coastal clam shacks.

Razor Clams

Long, narrow, tubular, resembling a straight razor. Shells are smooth and shiny, often brown or beige. Meat is tender, sweet, with a slightly chewy texture.

Habitat:

• Sandy beaches and shallow waters of the Atlantic and Pacific coasts.

Nutritional Notes:

• High in lean protein, low fat, contains vitamins B12 and D, iron, and selenium.

Culinary Uses:

• Best cooked: grilled, stir-fried, steamed, or baked.

• Excellent in Asian stir-fries or Mediterranean dishes with garlic and herbs.

Preparation Tips:

• Clean thoroughly, remove sand from siphon.

• Cook quickly to retain tenderness; overcooking makes them rubbery.

Fun Fact: Razor clams can dig into sand at remarkable speed, making them challenging to harvest.

Quahog / Chowder Clams

Large, hard-shelled clams with thick, dense meat. Chewy texture, robust briny flavor.

Habitat:

• Eastern US coast, especially New England.

Nutritional Notes:

• High protein, iron-rich, contains vitamin B12 and selenium.

Culinary Uses:

• Not suitable raw.

• Ideal for chowders, soups, and stuffing (e.g., New England clam chowder, clam cakes).

Preparation Tips:

• Scrub shells, soak to remove sand.

• Cook thoroughly in soups, stews, or baked dishes.

Fun Fact: Quahogs can live up to 40 years and are sometimes used in archaeology to study ancient diets.
