For best results, make sure your starter is bubbly and recently fed so the dough rises properly, and adjust fermentation time according to your kitchen temperature—warmer rooms shorten rise time, cooler rooms lengthen it. Hydration can vary slightly depending on your flour, so if the dough feels very stiff, add a tablespoon or two of water; if it feels overly sticky and slack, lightly flour your hands instead of adding more flour to the dough. Distribute the rosemary and Parmesan evenly during folds to avoid dense pockets, and avoid cutting into the loaf while it is still hot, as this can make the crumb gummy. This bread freezes well when fully cooled and sliced, and it’s excellent toasted, served with soup, or used for savory sandwiches.
