What is the difference between clams, razor clams and arselle?

Clams is a broad culinary term for edible bivalves. Razor clams, known in Italy as cannolicchi, have long narrow shells and a sweeter delicate texture. Arselle are small Mediterranean clams often used in Tuscany and Liguria for pasta, sautés and soups.

How should clams be cleaned before cooking?

Clams should be kept cold, scrubbed under cold water, and purged in lightly salted water when appropriate to help remove sand. Discard any cracked shells or clams that remain open and do not close when tapped.

What are the classic culinary uses for clams?

Classic uses include spaghetti alle vongole, sautéed clams with garlic and white wine, clam soups and chowders, risotto, seafood stews, grilled or baked clams, and shellfish appetizers.

Professional Product Summary

Clams are edible bivalve mollusks with a firm yet tender texture and a naturally saline liquor that enriches sauces and broths. They should smell fresh like clean sea water, not strong or fishy.

Origin, Tradition & Culinary Importance

Clams have been gathered and cultivated for centuries in coastal Europe, Asia and the Americas.

Throughout Mediterranean cooking, clams hold an important place because they offer sea flavor without the weight of richer fish or crustaceans. In Italy they are used in classic coastal dishes, especially in regions such as Campania, Lazio, Tuscany, Liguria and Veneto. Spaghetti alle vongole is one of the great pasta classics, built from garlic, olive oil, white wine, parsley and clam liquor.

Beyond Italy, clams are central to Portuguese, Spanish, French, Japanese, Chinese and American cuisines. Their value comes from three elements: their sweet flesh, the natural liquor released during cooking, and the wide range of sizes and species available for different uses.

In Tuscany and along the Tyrrhenian coast, small clams and arselle are appreciated for lighter pasta dishes, soups and sautés. Cannolicchi, or razor clams, offer a different shape and texture and are often used grilled, sautéed or lightly baked.

Varieties & Types of Clams

Different species and sizes serve different culinary purposes. The names below are practical culinary references.

Vongole Veraci / Manila Clams

Among the most common clams used in Italian cooking. They are medium-small, attractive, easy to open and excellent for pasta, steaming and seafood appetizers.

Little Neck Clams

Small tender clams prized for raw bars, steaming and delicate preparations. Their smaller size makes them ideal for elegant plate presentations.

Cherrystone & Quahog

Larger and meatier. Better for baking, stuffing, chowders and hearty soups. As clams increase in size they often become stronger in flavor and firmer in texture.

Arselle

Small Mediterranean clams associated with coastal Italian cuisine. They are excellent for light pasta dishes, sautéed shellfish and brothy preparations.

Cannolicchi / Razor Clams

Long narrow clams with a delicate sweet flavor and a visually distinctive shell. Very good grilled, lightly sautéed, breaded or served in refined shellfish plates.

Surf Clams

Larger ocean clams often used for chopped clam meat, chowders, stuffing or processing. Less delicate than small pasta clams but very useful in volume production.

Seasonality, Purchasing & Quality

Availability can be regional and increasingly supported by aquaculture, but quality selection remains essential.

Seasonality

Wild clam seasonality varies by species and coast. In many regions clams are considered best during cooler months, while modern sourcing and aquaculture provide more stable year-round supply. Restaurants should always buy according to local regulations, approved suppliers and current harvest conditions.

How to Buy Good Clams

Buy only from approved, reputable seafood suppliers.
Shells should smell fresh and marine, never sour.
Shells should be closed or close when tapped.
Avoid broken shells and obviously dry, gaping product.
Check harvest tags and keep shellfish identification labels as required.

Cleaning, Purging, Storage & Food Safety

Correct handling protects flavor, texture and guest safety.

Handling Guidelines

Keep clams refrigerated and covered with breathable material, never sealed airtight in fresh water.
Rinse and scrub shells to remove mud or debris.
When sandy, purge in lightly salted cold water for a limited time appropriate to the species.
Discard cracked shells and clams that stay open and do not respond when tapped.
Cook only until shells open; overcooking makes the meat tough.
Discard any clams that do not open during cooking.

Food Safety Notes

As with all shellfish, traceability matters. Harvest area documentation and refrigeration are essential. Shellfish can carry allergens and potential biological hazards, so time-temperature control must be respected from receiving through service. After cooking, serve promptly or chill correctly for later controlled use.

Clams are valued nutritionally because they are protein-dense and rich in iron, B12 and trace minerals. Nutritional values will change if butter, cream, breadcrumbs or rich sauces are added.

Culinary Usage

Clams contribute both meat and liquor, making them especially valuable in sauce-based preparations.

Pasta

Spaghetti alle vongole is the classic reference: garlic, olive oil, white wine, parsley and clam liquor. Small-to-medium clams are preferred.

Steamed & Sautéed

Excellent steamed with aromatics and wine, then finished with herbs, olive oil or butter. Ideal for appetizers and seafood platters.

Soups & Chowders

Clam meat and clam liquor build depth in soups, broths and chowders. Larger clams are often chopped for these uses.

Risotto & Rice Dishes

Clam liquor can enrich risotto or rice-based seafood dishes with a clean marine note.

Grilled / Baked

Razor clams, cherrystones and some larger clams can be grilled, broiled, breadcrumb-topped or stuffed.

Refined Seafood Plates

Clams work beautifully in tasting menus, shellfish appetizers and composed seafood dishes when paired with emulsions, herbs, cured pork or citrus accents.
