Avoid Baking in a Dirty Oven
We know how hard it is to clean your oven, but using a dirty one is a worse offense. One of the biggest mistakes bakers make is using dirty ovens to bake their delights. Take the time to clean out your oven at least once a month, and skip out on the self-clean feature while you are at it.
A dirty oven can cause your dish to cook improperly or even leave behind strange odors and tastes in the finished dish. The last thing you want is a funky-tasting cake. If something does go wrong with your dish, you may not even know what the cause was when you also have to factor in a dirty oven.
