Here, aromatic cardamom, which has a slight citrusy flavor, and a little dark rum give this easy-to-make moist cake an intriguing flavor. Once the batter is mixed, put the cake in the oven immediately, so none of the leavening power of the baking powder and baking soda is lost. Other berries, such as blackberries or raspberries, can be substituted for the blueberries.
