Through the Real Bread Campaign, I’ve met quite a few people who have said “Sod this”, quit their jobs, and become bakers. Ben MacKinnon is one of them. I first met Ben in the early days of his railway arch bakery, where he’d built an oven from salvaged materials. This is the basic recipe for the E5 Bakehouse’s signature sourdough. It depends on long, slow fermentation to develop a robust dough with a deep, complex flavour.
