In the southern US, especially in Virginia, deep-fried oysters are on the menu almost every day. These are fried in crispy cracker crumbs. They're a great starter with tartar sauce for dipping and go especially well alongside a crisp green salad.
Only buy fresh oysters from your fishmonger and ensure that the shells are tightly closed. You should eat them as fresh as possible. You can store them briefly in the fridge with the curved side down in a bowl covered with a damp tea towel.
