While you can make bread without a specialised bread maker, there are clear benefits to owning one. Making bread without one of them requires a lot of skilled kneading to get a good result, while a bread maker is effective at kneading the dough for you; although most chefs will claim that the results aren’t nearly as good.
Bread makers also allow you to change various settings with the devices, which means that you can have different settings for different types of breads. It can also be used to change the result of the same type of bread, but it is often better to set it the specific setting for the type you’re making, as playing around with it can be disastrous to your bread. The most user-friendly bread makers will have their settings named to specific types of bread to remove the guess-work.
