I think they only Fry them. Since the line is always so dang long, I have had time to sit and watch (And wait patiently).
I found another option though. The one I might purchase is this one!
GourmetSleuth - Potato Threader
More affordable, and it looks like it might actually make something I have been looking for, which is Onion Strings or Onion Threads.. I am talking about those nests of onions that are the thickness of like Kite String and then deep fried.. I love those things!
