Stop guessing why your sourdough goes flat. This worksheet helps home bakers diagnose the most common reasons a loaf spreads instead of rising, then guides you to the small adjustments that improve shape, oven spring, and consistency without changing flour brands every time. Use it before your next bake to spot weak dough, underproofing, overproofing, shaping issues, and baking setup problems fast. Built for everyday home bakers who want taller loaves, better structure, and more repeatable results with the ingredients they already have.
