Ingredients

• 2 cups (300g) Raisins, dark and golden
• 1 cup (150g) Currants
• 1 cup (150g) Prunes, pitted and finely chopped
• ½ cup (75g) Dates, pitted and finely chopped
• ½ cup (75g) Glacéed Cherries, finely chopped
• ¼ cup (30g) Mixed Citrus Peel, finely chopped
• 1½ cups (360ml) Dark Caribbean Rum (e.g., Myers's, Goslings)
• ½ cup (120ml) Port Wine or Dry Red Wine
• For the Browning (Burnt Sugar Syrup):
• 1 cup (200g) Dark Brown Sugar, packed
• ¼ cup (60ml) Water or Dark Rum
• For the Cake Batter:
• 1 cup (226g) Unsalted Butter, softened
• 1 cup (200g) Granulated Sugar
• 4 large Eggs
• 1 teaspoon Vanilla Extract
• ½ teaspoon Almond Extract
• 1 tablespoon Orange or Lemon Zest
• 2 cups (240g) All-Purpose Flour
• 1 teaspoon Baking Powder
• 1 teaspoon Ground Cinnamon
• ½ teaspoon Ground Nutmeg
• ¼ teaspoon Ground Allspice
• Pinch of Ground Cloves
• Optional: ¼ teaspoon Anise Extract or a pinch of Cardamom
• For the Rum Syrup (for Feeding the Cake):
• ½ cup (120ml) Dark Caribbean Rum
• ¼ cup (60ml) Cherry Brandy or Orange Liqueur (e.g., Grand Marnier)

Directions

1. Soak the Fruit (3 Days to Several Weeks Ahead):
   1. In a large, clean glass jar or airtight container, combine all the chopped dried fruits.
   2. Pour in the dark Caribbean rum and port wine. Stir well to ensure all fruit is submerged.
   3. Seal the jar tightly and store in a cool, dark place.
   4. Stir the fruit mix every few days. If the liquid level drops significantly, top off with a splash more rum. The longer the fruit soaks, the deeper the flavor of your cake filled with fruit.
2. Make the Browning (Burnt Sugar Syrup):
   1. In a heavy-bottomed saucepan, combine the dark brown sugar with ¼ cup of water or rum.
   2. Cook over medium-high heat, stirring until the sugar dissolves.
   3. Bring to a boil and continue cooking without stirring. The mixture will bubble, thicken, and darken. Watch carefully as it progresses from light caramel to deep amber, then to a very dark, nearly black color. This process can take 10-15 minutes.
   4. Safety Note: This mixture will be extremely hot! Once it reaches a deep, dark brown (almost black, but not burnt-tasting), carefully remove it from the heat.
   5. Immediately and very slowly add the remaining ¼ cup of water or rum, stirring constantly. It will bubble violently and steam. Stir until smooth.
   6. Allow the browning to cool completely before using. It will thicken considerably as it cools.
3. Prep the Pan and Oven:
   1. Preheat your oven to a low 275-300°F (135-150°C). This low-and-slow baking is key for the cake's dense, pudding-like texture.
   2. Grease and flour a deep 9-inch round or square baking pan (or equivalent volume loaf pans).
   3. Line the bottom and sides of the pan with parchment paper, leaving an overhang to help lift the cake out later. If you have a lighter-colored pan, consider double-lining the sides to prevent over-browning.
4. Mix the Batter:
   1. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy (about 3-5 minutes with an electric mixer).
   2. Beat in the eggs one at a time, incorporating each fully before adding the next.
   3. Stir in the vanilla extract, almond extract, and orange/lemon zest.
   4. In a separate bowl, whisk together the all-purpose flour, baking powder, ground cinnamon, nutmeg, allspice, and cloves (and optional anise/cardamom).
   5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
   6. Drain any excess liquid from your soaked fruit mix (you can save this rum for the feeding syrup!).
   7. Fold the soaked fruit paste and the cooled browning into the cake batter. Mix until the batter is uniformly dark and thick, ensuring the fruit is evenly distributed.
5. Bake the Cake:
   1. Pour the thick batter into your prepared pan and smooth the top with a spatula.
   2. Bake in the preheated oven for 80-90 minutes, or even up to 2 hours, depending on your oven and pan.
   3. To check for doneness, a wooden skewer or knife inserted into the center should come out with a few moist crumbs attached, but not wet batter. The cake will feel set but still very dense and moist.
6. Feed and Age the Cake:
   1. While the cake is still warm from the oven, poke small holes all over the top using a skewer or fork.
   2. Gently spoon or brush the rum syrup (dark rum + cherry brandy/orange liqueur) over the entire surface, allowing it to soak in. Use about half the syrup initially.
   3. Let the cake cool completely in the pan on a wire rack.
   4. Once cool, remove from the pan, wrap it tightly in parchment paper, then in aluminum foil.
   5. For optimal flavor, age the cake for at least 2-3 days. For a truly authentic experience, it can be aged for several weeks in the refrigerator, occasionally unwrapping to spoon a little more rum syrup over it. The flavors deepen beautifully over time.
