The process of preparing bivalve mollusks via the application of moist heat within a contained environment is a popular culinary technique. This method utilizes steam to gently cook the shellfish, resulting in a tender and flavorful product. For example, placing oysters on a rack above boiling water within a covered pot allows the rising steam to efficiently cook the oysters until their shells open.
This cooking method offers several advantages. It preserves the natural moisture and flavor of the oysters, preventing them from drying out. Furthermore, steaming allows for even cooking and is often considered a healthier option compared to frying or grilling. Historically, coastal communities have long relied on this efficient method to prepare fresh oysters.
