If you're going to make a classic fruitcake, conquer it with this foolproof recipe. Start your fruitcake the day before; candying your own citrus is well worth it. The result is gooey, moist, and dense. The rum taste is bold and delicious, but you can also use apple cider, if desired. This recipe makes four loaves that will keep for a month, so it's perfect for gift giving.
