Well this item could be good BUT if you're thinking about Mr.Iron. This would increase his dammage way to easily, since he's gathering most of the steak :).
That why I think @jarecy add this line (:for every steak the tower HOLDS") to fix the problem that Mr.Iron would make.
Else this item look average since it's only avaible at round 70/100, because it's purple and at this time crit doesn't affect so much the game play yet. I think the purple item should have more impact than the white one. Because pan juices won't serve a lot but it's going to give a free item/run.
