Before you raise your eyebrows in suspicion of this cake’s unusual secret ingredient, let me argue its case. I was served this Dark Chocolate and Beetroot Cake upon arrival in London last year. It was baked lovingly by my cousins, drizzled with dark chocolate ganache and intricately decorated with a white chocolate welcome message. I was so taken aback by how incredibly rich and velvety the first bite was. The idea is not to actually taste the beetroot, but there is a dark, seductive, earthy tone to the cake that is utterly delicious.
