What is the Difference Between Mussels and Clams?

Mussels and clams are both popular shellfish used in various culinary dishes, but they have some key differences in appearance, flavor, and texture:

1. Appearance: Clams have rounded shells, similar to the shape of a fan, while mussels have longer shells with an oblong shape. Clam shells are stout, smooth, and oval-shaped, while mussel shells are thin, rough, and either black, dark blue, or brown in color.
2. Habitat: Clams can be found in both freshwater and saltwater environments, while mussels are typically found in freshwater and saltwater habitats, attached to a substrate in groups.
3. Flavor: Clams have a stronger flavor that leads with saltiness and a noted sweetness. Mussels, on the other hand, have a milder taste with a more pronounced sweetness and less salty flavor.
4. Texture: Clams have a firmer chew compared to mussels.
5. Varieties: There are over 150 different kinds of clams, with the most common edible varieties being quahog, geoduck, manila, and soft-shell clam. Mussels are typically farmed in more controlled environments.

While clams and mussels can be used interchangeably in recipes, they do taste slightly different, especially when comparing mussels to the sweet varieties of clams. However, if you're a fan of both and don't have access to one, you can certainly swap in the other in a recipe, and the cooking steps will be similar.
