Put the dried fruit, zest and juice and alcohol into a large bowl and leave for twenty-four hours stirring occasionally.
Heat oven to 150C / 300 F / Gas Mark 2. Put a damp cloth onto the work surface and place your largest mixing bowl on top. Add the softened butter, sugar, treacle and almond essence and cream together.
Crack the eggs one by one into a small bowl to check they are fresh, then combine and whisk together. Sift the flour, spices and baking powder into another bowl.
Add the egg mix in batches and beat into the butter and sugar mix. Add a couple of tablespoons of flour with each batch to prevent the mix from splitting. When all of the egg is mixed in add the remaining flour and spice mix and fold together until thoroughly combined. Add the soaked fruits and flaked almonds and gently stir together.
Tip the cake mix into your prepared cake tin, and tap on the work surface to knock out any pockets of air. Place in the centre of the oven bake for an hour, cover the top with two layers of baking paper and turn the oven down to 140C / 275 F / Gas Mark 1 and cook for around two and a half to three more hours or until a wooden skewer inserted in the cakes centre comes out clean.
Remove the cake from the oven and allow to cool. To feed your cake poke holes in it with a skewer and spoon over tablespoons of your chosen alcohol, wrap in fresh baking paper and tin foil and place in a biscuit tin or plastic tub. Feed the cake with two tablespoons of alcohol every fortnight, until you marzipan it before icing.
