Naturally leavened for 48 hours for a rich, complex flavor with a moist, open crumb, this panettone is studded with juicy raisins and candied orange and citron. The dough is worked by hand at the Perbellini bakery in Verona and is gently rested upside down after baking to achieve its towering height. It comes in a custom-designed tin inspired by classic Italian design that will be a beloved keepsake long after the panettone is gone.
