Preheat oven to 325 degrees F. Coat a baking sheet with cooking spray. Combine dried fruit, candied peel (or citron) and brandy (or rum). Let stand for 15 minutes.Advertisement
Meanwhile, combine flour, brown sugar, sugar, baking powder, baking soda, cinnamon, nutmeg, allspice and salt. Whisk together eggs, egg white and vanilla in a small bowl, and add to the flour mixture; mix until almost smooth. Stir in the fruit and brandy mixture.
Working on a floured surface, shape the dough into 3 logs, each about 14 inches long and 1 1/2 inches thick. Place the logs on the prepared baking sheet and bake until firm to the touch, 25 to 30 minutes. Transfer the logs to a rack to cool. Reduce the oven temperature to 300 degrees .
Cut the logs diagonally into 1/2-inch-thick slices. Stand the slices upright on the baking sheet and bake until light golden, 50 to 60 minutes. Let cool before storing.
