Editor's note: The recipe and introductory text below are from Jamie Oliver's book Jamie's Italy. I've always thought of crostini as small bruschette but this isn't completely correct, as they are usually made with white bread instead of sourdough. I'm told that in the old days the bread would have been so stale that it would have to be soaked in a little stock or juice to make it chewy and edible again, but don't worry. In this day and age you don't have to do this. In Italy they simply grill a half-inch slice of ciabatta, rub it with a cut clove of garlic, drizzle it with oil, and season it with salt and pepper.
