she is gorgeous. What is she like if you put your hand near her without the food on it?
I would try that if you haven't already. Let her get used to just your hand.
I often do this with a new hamster by setting up a small box with some hamster toys in it and transport them from the cage to the box with a mug/jug (what you are already doing) Let her roam around the box, but keep placing your hand in there so she has to walk over it, see how that goes? Any sign of her going towards your hand to bite it, move it out the way.
