To fix a gummy crumb when your starter is healthy and active, you need to adjust your fermentation or baking process. A gummy texture usually happens because the dough is under-fermented, under-baked, or cut open too early.
Here is how to fix it based on your workflow:
1. Extend Your Bulk Fermentation (Before the Fridge)
You are doing your stretch and folds, but you likely need to let the dough rest at room temperature after the folds before putting it in the fridge.
• The Fix: After your last stretch and fold, let the dough sit on the counter for another 2 to 4 hours (depending on your room temperature) until it expands by about 30–50%, feels puffy, and shows a few surface bubbles.
• Why: The fridge slows yeast down instantly, but bacteria keep working. If it goes in the fridge too soon, it stays under-fermented, leading to a dense, gummy interior.
2. Adjust the Post-Fridge Step
Sourdough does not need to warm up to room temperature before baking. In fact, cold dough is easier to score (cut) and holds its shape better in the oven.
• The Fix: Bake the dough straight from the fridge into a fully preheated oven.
3. Check Your Baking Time & Temperature
Even if the bread rises, it may not be fully baked into the center, leaving the starches wet and gummy.
• The Fix: Preheat your oven and Dutch oven to 230°C–245°C for 45 minutes. Bake covered for 20–25 minutes, then remove the lid, drop the temperature to 210°C–220°C, and bake for another 20–25 minutes until the crust is deeply browned.
• Tip: If you have a digital thermometer, the internal temperature should reach 96°C–99°C before you pull it out.
4. The Golden Rule: Wait to Slice
• The Fix: Let the loaf cool completely on a wire rack for at least 2 hours (ideally 4 hours) before slicing.
• Why: The bread keeps cooking on the inside while it cools. Slicing into a hot loaf releases the trapped steam instantly, turning the remaining moisture into a gummy gel.
To fine-tune this, let me know:
• What room temperature you are working in (since warmer rooms ferment much faster)
• How long you let the dough sit on the counter in total before it goes into the fridge
I can give you the exact timing adjustment for your next bake!
