Cake with caramel and rum-soaked raisins: Prepare the Kamado BONO grill for indirect cooking. Light the charcoal with a fire starter, place the stainless steel grates on the grill, and then set a baking stone on top. Wait until the temperature reaches 180 degrees Celsius. Adjust the top and bottom air vents to maintain an even temperature throughout the cooking process.
Pour rum over the raisins and let them soak for 3-4 hours.
Beat the room-temperature butter with a pinch of salt until smooth. While beating, add one egg at a time, making sure to mix well after each addition. Stir in the condensed milk and caramel, then pour in the milk. Sift the flour with baking powder and gradually mix it into the batter. Add the rum-soaked raisins, mix everything well, and pour the batter into a baking pan greased with butter. Bake for 40 minutes at 180°C.
Once baked, sprinkle the cake with powdered sugar.
