I may be a little late, but it just takes a little manuevering of the camera. The way I did it was I ran in circles around the counter and each time I passed, tried to stir the pot at least once as I ran (if I couldn't hit "E" before passing it, I just tried again on the second loop so as not to slow down too much). Eventually, it got to a point where I could stir even if I wasn't near the pot; just keep an eye out and hit the key whenever you see the cursor turn green.
Hope this helped!
