Crusty boules and batards are wonderful, but do you sometimes want a nice soft sandwich bread to replicate that timeless, comfortable and comforting PB & J of your childhood? This should do it, and it’s a lot better than Wonder Bread (because it’s made with dough — and sourdough! — not batter).
As with most pan breads, removing the loaves from the pans once their structure is set, and letting them finish the bake standing directly on the stone, helps the side crusts brown. If you don’t have a stone, you can place them right on the oven rack if you don’t mind a few grooves on the bottom of the loaves, or on a baking sheet that has been preheated with the oven.
Size matters! If your loaf pans are not 8.5 x 4.5 inches, you will need to adjust the amount of dough proportionally, with respect to the volume of the pan, to avoid loaves that are too short or tall. If your pans are 9 x 5 inches, use about 880 grams of dough per loaf.
