Common Mistakes to Avoid
Making sourdough Japanese milk bread can be tricky, but avoiding common mistakes will ensure a successful bake. Here are some pitfalls to steer clear of:

- Skipping the tangzhong method: This step is crucial for achieving the soft texture characteristic of Japanese milk bread. Make sure to prepare the tangzhong correctly for best results.
- Not measuring ingredients accurately: Baking is a science, and imprecise measurements can affect the outcome. Use a kitchen scale for accuracy.
- Overproofing the dough: Allowing your dough to rise too long can result in a collapsed loaf. Follow the timing guidelines closely for optimal results.
- Ignoring temperature control: Temperature affects yeast activity. Ensure your ingredients are at room temperature, especially the milk and butter, for even mixing.
