Frozen cooked white clam whole shell in Tomyum sauce

The product is already well cooked but consumers are advised to re-heat before eating. It could be done in one of following ways:
+ Fully defrost the products without leaking the vacuum bag -> steam heat or put into microwave or in boiling water for 2-3 minutes until the shell open -> cut the bag and eat.
+ Put whole bag without defrosting into microwave or boiling water for 3-4 minutes until the shell open –> cut the bag and eat
(When using microwave, make a tiny hole on bag to release vapor.)
+ Or it can be done in other ways at consumers’ convenience and safety.
