Professor Crumb’s Starter SOS: A Sourdough Troubleshooting Guide

Is your sourdough starter barely rising, smelling strange, covered in liquid or simply leaving you unsure what to do next?

Professor Crumb’s Starter SOS is a calm, practical troubleshooting guide for real-life bakers. Instead of relying on a perfect clock, you’ll learn to compare what you can see, smell and feel before choosing the next useful step.

Inside this 12-page digital guide, you’ll learn:

• How to recognize common starter stages

• What bubbles, texture, smell and liquid can tell you

• What to try when your starter is sluggish or not rising

• What it means when your starter rises and then falls

• How to respond to hooch and signs of hunger

• Which warning signs mean the entire starter should be thrown out

• When your starter may be ready to use for bread

• Simple feeding and recovery guidance without rigid promises

Created especially for beginners, busy bakers and anyone who has ever stared at a starter jar wondering, “Is this normal?”

IMPORTANT SAFETY NOTE

This guide is for educational purposes and cannot evaluate food safety through a screen. If your starter has visible fuzzy mould, pink or orange discolouration, or a genuinely rotten or putrid smell, throw out the entire starter and clean the container before starting again. When you are genuinely uncertain about contamination, replacing the starter is safer than taking a food-safety risk.
