My brother turned 30 and I wanted to make him a cake that represented a fond memory that I had of him. I remember very vividly that he was baking a cake with my mother one day – he couldn’t have been more than 4 years old – and as she was mixing the batter he emptied a bottle of blue colourant into the mixing bowl. With little my mother could do she just mixed it in and baked it. What came out was the bluest of hues in a cake either of us had ever seen. Beautiful really. A year ago red velvet was the craze, but I like to imagine that my brother had invented the blue velvet before any craze. Needless to say, the cake had white cream cheese frosting on the outside and he had no idea it was blue inside until he cut a slice. Of course he just laughed and quietly shook his head at his discovery and the thought that all his friends were about to eat very blue cake.
