Traditional bread recipes do not require conversion when using a KitchenAid mixer. The mixer handles the kneading of the dough, so there is no need to do it by hand.
Kneading dough can be a time-consuming process, but it keeps bread from becoming a heavy, dense lump. It strengthens the glutens that trap air bubbles, and it also lets the dough rise. Using the dough hook attachment on the mixer lets cooks perform this task automatically, but otherwise the bread recipe remains unchanged when using the KitchenAid stand mixer. The stand mixer should be its second speed and never above that when kneading bread.
