Yes raw , but I must admit I like them all kinds of ways. One great way if or for people who must have them cooked I stumbled on down in Louisiana eating Crawfish that
@Steel was cooking for us. He showed up with a gunnysack of oysters and after we shucked and ate as many raw ones we wanted. He cooked the crawfish and I scrubbed what oysters were left and we dumped them in the crawfish boil. I tell you them cajun seasons made the oyster phenomenal

it was a hreat little Rocket get together. Out on the grand isle.
