I had to get drunk to eat raw oysters on the 1/2 shell, but it was tasty, sobered up and had some more. Caught fresh in the Chesepeake bay that morning, brought to a party and shucked it in the back yard. He ran a oyster barge.
I’ve had raw oyster on the half shell, shooters.
Never could figure out the purpose to swallow them quickly so as not to taste them. I prefer to chew them up. But better to chew them cooked in some manner.
