I have tried probably a dozen different recipes using garlic powder, cayenne, black pepper, onion powder, etc. etc. I like to buy the tubs of pre-shucked, small oysters (or cut large ones in pieces). I usually pick some up from Lytle's when we get out to Ocean Shores. They are perfectly seasoned with just the sea salt. I line my smoker racks with parchment and smoke away. Flip them over an hour into smoking and do the other side for about an hour. They come out perfect. I usually smoke at about 175 or so.
