When making pumpkin sourdough bread, ensure your sourdough starter is active and bubbly to achieve the best rise. If the dough feels too sticky, lightly flour your hands and the work surface to make handling easier. Additionally, using a Dutch oven helps create a steamy environment, which is crucial for a crispy crust. Adjust the water content slightly if your pumpkin puree is particularly wet or dry, and remember that resting times can vary based on room temperature and humidity.
