Bulk Rise
Cover the bowl with plastic wrap and let rise overnight at room temperature (68 F) until double in size, about 10-12 hrs. Please refer to the Baking Schedule above for additional rise time options.
Shape the Dough
In the morning, coat an 8.5×4 inch loaf pan with butter.
Remove the dough onto a lightly floured work surface. Gently flatten the surface to release any large air bubbles.
Roll the dough into a log tucking the ends underneath. Rest for 5-10 minutes. With floured hands, gently cup the dough and pull it toward you to tighten its shape. Using a bench knife, place the dough into the loaf pan seam side down.
Second Rise
Cover the dough with lightly oiled or buttered plastic wrap. Let rest at room temperature until it has risen to about 1-inch above the rim of the pan (check the height by looking at the domed center portion of the dough). You are not looking for it to double in size. For timing, this can take anywhere from 1 1/2-2 hours (or more!) depending on temperature and the amount of sourdough starter used. Remember, the warmer it is, the faster the dough will rise. Refer to the “helpful tips” at the top of this post.
Preheat your oven to 375 F. Note: For higher oven spring, preheat to 500 F instead. Reduce to 375 F once the dough goes into the oven and bake as directed.
Bake the Dough
Bake the dough on the center rack for about 45-50 minutes, or until golden brown.
Cool in the pan for at least 10 minutes, and then transfer to a rack to cool completely.
This sandwich loaf will stay fresh for up to 3 days, stored in a plastic bag at room temperature.
Notes
For best results, please weigh your ingredients with a scale instead of using measuring cups.
Here’s why: weight and volume measurements are not equal, only approximate! This is especially important regarding the sourdough starter. If your starter is very bubbly, 1/4 cup might only weigh 30 g which is too little for this recipe (you need 50 g). The dough will take forever to rise! Same goes for the flour… 4 cups might end up weighing way over 500 g depending on how tight the flour was packed into the cup. You’ll end up with dry dough.
I used Whole Foods 365 Everyday all purpose flour for this recipe. King Arthur and Trader Joe’s ap flour will work as well. If using another brand with a lower protein content (i.e. Gold Medal, Pillsbury, Heckers) consider reducing the total water amount by 15 g.
