Wonderfully moist and tangy, this zesty cake can be made with seedless clementines, satsumas or tangerines, depending what’s in season. It’s a lovely summer pudding made from polenta and natural yogurt, which makes it one of the healthier options, too. You’ll know it’s cooked when an inserted skewer comes out clean – about an hour should do it.
