Learning how to clean clams properly is one of the most important skills for anyone who enjoys cooking fresh seafood. Clams are delicious, nutritious, and widely used in cuisines around the world—but because they live buried in sand and filter seawater, they often contain grit, debris, and impurities that must be removed before cooking.
This long-form guide is written using food safety standards, professional culinary practices, and real kitchen experience. It explains how to clean clams before cooking, how to clean clams from sand, how to clean clams by soaking, how to clean clams with cornmeal, and how to clean clams in the shell. You’ll also learn how to clean clams before steaming and how the process compares when cleaning clams and mussels together.
Understanding Clams and Why Proper Cleaning Is Essential
Clams are bivalve shellfish that live partially buried in sand or mud, filtering water to feed on microscopic organisms. As part of this natural process, they accumulate sand, grit, and sometimes bacteria inside their shells.
According to food safety research from the FDA, improperly cleaned shellfish is one of the leading causes of unpleasant texture issues and foodborne illness in home-cooked seafood. Proper cleaning improves both safety and eating quality.
