Can you cook frozen clams if they are open after thaw?

Yes, you can cook frozen clams that are open after thawing, but it's essential to ensure they are still safe to eat. Generally, clams that remain open when tapped gently should close, indicating they are alive. If they do not close or have an off smell, it's best to discard them. Cooking clams that are still alive will ensure they are safe and delicious to eat.
