A quahog is a type of clam found off the Atlantic coast from Canada to Florida, but is most common between Cape Cod and New Jersey. Quahogs are known as “hard clams” or “hard-shelled clams” in most of the country. Quahogs are mollusks like soft-shell clams, mussels, oysters and scallops. Some quahog eaters prefer them raw, but you can also steam quahogs to serve in the half shell or in soups and stews.
Rinse the clams under running water to clean away any sand. Throw away any clams that don't close when touched.
Add 1 to 2 inches of water to a pot and place it on your burner under high heat.
Add your quahogs to a steamer basket and set it on top of the pot once the water has begun to boil. If you do not have a steamer basket, you can place the quahogs directly in the water in the pot -- do not fully cover them with water.
Place a lid on top of the steamer basket and steam the clams for 5 to 10 minutes, or until the shells have just popped open. Don't overcook, or the meat will toughen.
Discard any clams that haven't opened, and serve as desired.
