Julissa Roberts shows how to shuck an oyster. She shows us how to determine whether the oyster is safe to eat, how to shuck the oyster, and then one way to prepare a plate of oysters. If you don't properly check the oyster, and clean it, you could get a mouth full of sand, or get an oyster that smells like rotten fish. To check whether the oyster is good, smell it, it will smell like rotten fish if it's bad. Then tap the oyster on something solid, if the oyster is dead, it will sound hollow, and if the oyster's mouth is open, tap the flat upper shell. If the oyster is alive, the shell should close tightly, if the oyster is dead, it won't do anything.
