Getting to know how your oven bakes bread is just as important as your bread making technique. If you’re in any doubt use a separate oven thermometer to test the accuracy of your oven’s in-built thermometer. Preheat the oven with the thermometer on the shelf you will bake on, then adjust the oven temperature dial until the thermometer reads the correct temperature for your recipe. You should then be guaranteed correct baking times.
Every oven will bake good bread for you, but a fan oven can often darken the crust too much, so if you have the option I would recommend setting your fan oven to the top and bottom heat only with no fan assistance and using the non-fan temperatures in the recipes. Be aware of the hot spots in your oven and consider positioning a shelf at the very top of the oven and adding an empty baking sheet to it at the same time as you put your loaf in to bake. The sheet will conduct the heat evenly over the top of your loaf and prevent it from scorching on the top.
