Begin by rehydrating the dried fruits. Place these in a large pan and add the butter, sugar, lemon juice and zest, orange juice and zest, and bourbon. Cook over a medium heat until the butter has melted and the mixture is boiling. Lower the temperature and simmer for about 5 minutes. Then tip the contents into a large mixing bowl and allow to cool for about 30 minutes.
7 cups mixed dried fruit, 1 cup unsalted butter, 1 cup light brown sugar, ½ cup bourbon, 1 lemon, 1 orange
Meanwhile, preheat the oven to 300°F (150C/130C Fan) and line the bottom and sides of a deep sided 8" or 9" cake pan with a double layer of parchment paper.
Once the fruit mixture has been allowed to cool, add the flour, ground almonds, spices, vanilla and eggs to the mixing bowl and stir thoroughly with a spatula or wooden spoon to combine. Take care to ensure there are no clumps of flour left unmixed.
4 eggs, 1 teaspoon vanilla extract, 1¼ cup all purpose flour, 1½ cup ground almonds, 2 teaspoon ground cinnamon, 1 teaspoon ground nutmeg, ½ teaspoon ground allspice, ¼ teaspoon ground cloves
Pour this into the prepared cake pan and bake in the lower half of the oven for 2 hours until a skewer comes out clean.
Remove from the oven and use a toothpick to make holes all over the top of the cake. Spoon a couple of tablespoons of rum over the top and brush so that this soaks into the holes.
Allow the cake to cool in the pan, before removing and peeling away the parchment paper.
Store the cake in an airtight container, wrapped in parchment and feed with 2 tablespoons of rum every week until about a week before you are intending to serve.
