Here are some helpful solutions for the common causes:
Air circulating around the loaf allows the steam built up inside the bread to evaporate. If the bread is kept in its baking pan, it will become soggy and look and taste doughy.
If the bread has not finished baking by the maximum time indicated in the recipe, the oven thermostat may be off. Oven thermostats can vary over time, requiring adjustments by the baker or calibration by a professional. To insure the correct temperature each time you bake, always use an oven thermometer. Place it in the center of the oven. Adjust oven dial up or down to correct the oven temperature.
