RE: Tasty Fries
Okay, deep-fried potato buds. I'll settle for Pringles, maybe once every 5 years.
Actually, there have been other attempt at french fry machines. One I know of was a product backed by a business partner of my Dad's in the 60s. Idea was a fresh fry vending machine at high traffic retail stores, typically discount houses like Zayre (if you don't remember them, think KMart). The prototype of this machine did work pretty well. You could put your money in and watch it make fresh fries.
But the problems were numerous. Everything was fresh if the thing got traffic, but if not, there were problems holding peeled potatos, so they had to add a peeling process. Of course it required venting which most retail stores didn't have. And in most places it fell under food prep laws which created a regulatory hurdle most retailers didn't want to face. (This was in the days when many discounters did not have snack bars, and if they did have one, why would they need a french fry vending machine?)
I spent a lot of time as a kid playing with the half-built shells of automatic french fry machines.
