Your dough is not misbehaving. It is doing exactly what that temperature demands, on a schedule written for a cooler room. Almost every sourdough recipe was timed in a kitchen cooler than yours. In a warm room the same dough reaches the same point sooner, so following the clock produces a slack, over-fermented mass and a flat loaf — and the common fixes, more flour or less starter, address the wrong variable. This guide replaces the schedule with two things that travel: dough temperature and baker’s percentages. It works one loaf through completely, including the arithmetic most books skip — a 100 g starter at 100% hydration contributes 50 g flour and 50 g water, which is what makes the hydration figure come out at 68% rather than the number on the recipe. 32 pages, 14 tables, 15 references, 13 cited inline. The correction this guide is built on If the dough is running away in the heat, just use less starter and keep the same timings. That changes the prefermented flour percentage, which changes the timing as well — so you have altered two things and still have no reference point. The guide’s position is that a percentage endpoint borrowed from a cooler process should not be applied mechanically to a warmer one, because the point at which a dough should leave bulk depends on the whole process, including dough temperature and the intended final proof. A warm loaf also continues fermenting as it cools, which a schedule written for a cool kitchen never had to account for. Measure the dough, not the clock. What it answers How do I calculate sourdough hydration with the starter included? How do I keep dough cool without a proofing fridge? How do I know my starter is ready to use? Should I retard the dough in the fridge? How do I bake and judge the loaf?
