I have spiral dough hook on my kenwood but theres a problem that these just dont get all the ingredients together into a ball
So I usually get the handle of a wooden spoon, mix the ingreidents until its rough ball, then put it in the kenwood dough hook mixer. It does good job, but it seems like a hassle. I believe Petezza had this issue to, and he used the paddle attachment to get the ingreidents together then the dough hook. Thats just more cleaning up to do.
But I prefer to do it all by hand. No need to wash the big glass bowl that my kenwood has.
Many people love kneading by hand its theraputic. But if its a sticky dough I know what you mean I hate it getting stuck and finding dried up dough mix on my hand the next day.
