So far I've roughed up a basic shape and simple movement (not yet operated by one mechanism so in the video I'm moving the bits by hand)
The stirring mechanism is a simple rotating wheel and the hands are moved by the brass rod (which will become the spoon), arm joints are just string which seems to give a nice loose movement.
I may end up with her stirring one hand and have the other waving over the cauldron if I can figure out a mechanism.
The head just nods up and down and this will eventually be linked to the same mechanism as the cauldron.
Here are a few close ups
