What is the Difference Between Clam and Cockle?

Clams and cockles are both bivalve mollusks, but they have some differences in terms of appearance, habitat, and taste. Here are the main differences between clams and cockles:

1. Shell shape and texture: Clamshells are smoother and can be thicker, while cockle shells have a slightly ribbed texture and are more rounded or heart-shaped when viewed from the side.
2. Size: Cockles are generally smaller and more uniform in size, while clams can vary significantly in size.
3. Habitat: Clams can live in both freshwater and saltwater reservoirs, as well as some brackish waters, while cockles are only found in saltwater waters.
4. Taste: Clams are more common and slightly less sweet than cockles. Cockles are known for their sweet, tender meat without the overwhelming brininess that can turn people off from other shellfish.
5. Edibility: Clams can be eaten raw, but cockles must be cooked thoroughly before consumption.
6. Culinary usage: Both clams and cockles can be used interchangeably in most cooked recipes, such as steaming or boiling. However, due to their smaller size, you may need to use more cockles than clams in a recipe, with a recommended ratio of three to five cockles for every clam.
