Haven’t made this since high school. My cousin told me back then about a cake he sort of made up that was just rhubarb tossed with some ginger in a pan, and covered with sponge cake mixture. A guy at work has a surplus of rhubarb, so I went over yesterday to grab some and this is what I made. I don’t have my cousin’s sponge cake recipe anymore but I looked up another and the cake is fantastic. I am of course sharing it with my colleagues as having a pan full of cake all to myself would be a dangerous thing indeed.
