I wrote an add-on that adds a button to the Provisioner window, wherein you can craft as many Trotter Pies as you have the ingredients for, with a single button press. Now you can cook (in-game) and work on your knitting project (next to the keyboard) at the same time! (What, doesn't everybody do that???)
