I've never seen very large oysters served raw. I've also never known anyone who dared order them other than in a coastal town (I would NEVER even contemplate eating oysters in this land-locked state, for example). But, I don't know, nobody I know has actually chewed an oyster, they just swallow them whole, the way you do a shot of something that tastes nasty. I've never tried them. I watch this process and can't see any reason to do it. I've tried clams raw...nobody told me to just swallow, so I chewed...and chewed...and chewed...did I mention raw clams are very chewy?

The taste didn't bother me (I ate it raw because we went clamming and I was the only one to find any clams, and my mom wasn't going to boil up water to cook the few clams I dug up, but I insisted on eating the clams I dug, so she told me to eat them raw if I wanted them so badly...so I did

), they were just chewy. Nothing bad about it, just nothing to compel me to want more of them. I imagine oysters are likely the same. I HAVE eaten cooked oysters, and had to spit it out. It was in some sort of oyster cake (like a crab cake, but with oysters). Oh, that was just horrid. I didn't expect it to be so bad. I had never encountered seafood I didn't like before then, and never since either.
