Stand mixer for kneading dough
I'm currently using my bread machine to knead dough, but that's the only thing I ever use it for any more. I have a nice (circa 1940s) Kitchen Aid stand mixer: all metal construction. I think it's the professional edition since it has the ring that raises the bowl up and down, rather than the head that lifts out of the bowl.
I have several attachments for it, but none that look like the dough hooks I'm seeing for the current machines. In addition to the beater and wire whisk, I have what looks like a pastry knife. Would this work for mixing dough, or do I need to invest in a dough hook?
Once I get the correct accessory, how long do you generally knead bread with a stand mixer? How do I know when it's done?
Thanks for any advice. I'd love to get away from my dependency on the bread machine and get into making some more novel types of breads.
