Moisturize the Raisins: Begin by soaking the raisins in rum for about 30 minutes. This allows them to absorb all the delicious flavors.
Prepare the Cake Batter: In a bowl, melt the butter and mix it with the sugar until it’s smooth and creamy.
Incorporate the Eggs: Add the eggs one at a time into the mixture, ensuring you beat well after each addition.
Add the Raisins: Carefully integrate the rum-soaked raisins into the batter, stirring gently to mix.
Combine Dry Ingredients: Sift together the pastry flour and baking powder, then mix this dry combination into the wet ingredients until you have a smooth batter.
Bake the Cake: Grease a rectangular cake mold and pour your batter into it. Place it in a preheated oven at 170°C (340°F) for 40-45 minutes, or until a toothpick inserted comes out clean.
Cool the Cake: Once baked, let the cake cool in the mold for about 5 minutes before transferring it onto a wire rack to cool completely.
Final Touch: For a delightful finish, sprinkle some icing sugar on top of your cake before serving to add a sweet touch!
