Can I cook clams that are already open?
Give any open-shelled clams a tap, and if they don’t shut, discard the clam (soft-shelled clams will stay slightly open; thanks to their long neck, they can’t close completely). Clams must remain alive until cooked, so make sure that they’re packed in netted or perforated bags to prevent smothering.
Are open clams before cooking bad?
2 Answers. Before steaming the clams, they should all be closed. If any of your clams are open, give them a tap and if they stay open, then it is bad and you should take it out of your batch to prevent it from ruining the other clams. After you have steamed the clams, most of them should be open.
Will clams open if they are dead?

Are open frozen clams safe to eat?
Frozen clams certainly would be killed, and so wouldn’t open upon steaming. The thing about never refreeze is almost certainly a palatability issue, not a safety issue, as long as they stay in the safe zone (under 40 degrees F) and are not unfrozen for very long–but clams are highly perishable.
