James Morton charmed us on Bake-Off a while back with his imaginative show-stoppers combined with a scientific approach to baking. Since then he has amassed a large following on social media, founded a popular baking blog, and written four books – all while practising full-time as a doctor! His latest book Super Sourdough introduces us to the magic of the tastier, more natural bread which we are eating more and more of. It’s much more than simply a food: sourdough is a science. So who better than Dr James Morton, baking pedant and fermentation fanatic, to explain the basics for both the uninitiated and more experienced bakers.
