It's absolutely true. The cake is delicious as is, but if you want a simple syrup glaze, boil 1/4 cup water with 1/4 cup granulated sugar. The pot should be removed from the stovetop once the water has boiled. Stir in 1 tablespoon of lemon juice. Once the cake has cooled completely, brush the vanilla glaze over the top and allow it to dry completely before adding the syrup.
