Foods that look like coins or cash or are gold in hue—like mandarins, dumplings, cabbage, cornbread, lentils, and greens—are thought to help bring you prosperity in the new year. Germans eat cute marzipan pigs for an auspicious start to the new year—or try their more daring good luck dish: pickled herring. And at midnight, you can follow the Spanish tradition of popping 12 grapes in your mouth, one for each stroke of the clock, to help you get a fresh start for the new year.
