Rhubarb and ginger stem polenta cake

I finally found the perfect excuse to christen my new square tin with an idea I’d been deliberating about for weeks: putting ginger stem with rhubarb to make a delicately sweet and aromatic tray bake. The slight tartness from the rhubarb and heartiness from the polenta lend themselves well to an uplifting dessert apt for the spring months ahead. Making this was the first time I had ever improvised with both the amounts and ingredients of a cake (I normally go by the books). But it turned out to be a storming success, which is why I’m sharing it with you all. Give it a go!
