Welcome to Master Crumb
I created Master Crumb to share everything I've learned on my sourdough journey. From my first failed loaf—dense, gummy, barely edible—to finally achieving that perfect ear and open crumb, I've documented the techniques, mistakes, and discoveries that transformed my baking.
The calculator here is the tool I wish I had when starting out. The guides are answers to questions I asked countless times. Whether you're mixing your first starter or chasing the perfect crust, I hope what I've learned helps you on your own path.
