In Vietnam, a type of clam called “hàu” (also spelled as “hó” or “haeu”) is commonly consumed. While not exactly the same as European cockles, hàu are a type of small
saltwater clam that belongs to the genus Meretrix and are widely cultivated in Vietnamese waters.
Hàu clams have a more elongated shape than European cockles, with a thicker shell and a slightly sweeter flavor. They’re often cooked in various ways, such as steaming, boiling, or grilling, and served as an appetizer or side dish. In some regions of Vietnam, hàu is also used in soups, stews, and sauces.
In Vietnamese cuisine, hàu is considered a delicacy and is often paired with other ingredients like chilies, garlic, ginger, and herbs to enhance its flavor. The most popular way to eat hàu in Vietnam is probably as “hàu nướng mỡ hành” (grilled hàu with butter and fried shallots), which is a simple yet flavorful dish that showcases the clam’s natural sweetness.
