There's a quote that says "He was a brave man that first ate an oyster" and damnnnnnn that rings true when you look at them. Oysters rank HIGH up there on the "World's Ugliest Foods" list, which is why so many people patently refuse to eat them. Screw those scaredy cats—anyone who slurps their first oyster is hooked. They're delicious, they're light and fresh, and they basically have zero calories. Find a seat at an oyster bar and have a guilt-free happy hour snack, why don't you?
And once you get obsessed (which you will), you'll become more well-versed on which types of oysters are the best (East Coast all the way, baby), which are sweeter, which are brinier, which are massive, and everything else. Since there are so many deep sea nuances associated with oyster-ology, you might be well-served to start documenting your briny adventures, with this Oyster Tasting Journal ($5, 33 Books).
