A practical ebook for sourdough beginners whose loaves spread wide, stay dense, and never recover in the oven. Stop blaming the oven — the real issue happened earlier. This guide teaches you to read your dough's strength, gas, and structure before the bake, so you can diagnose the weak point and fix flat loaves for good. Covers: rough mixed dough, under-fermented bulk, weak shaping tension, and saggy proof as the four main failure points.
