Unfortunately, when you look in history you’ll find that potatoes are introduced in those areas around 1735. So, as nice that story is, it’s not possible. Fries where generally known in the 1900’s here in Belgium, but the real story on fries is sadly lost in history.
Dudes, if you’re at a McDonalds, those are French fries. For the rest, just call them fries.
Every so many years you can bid on one (or both) of those shacks to start making and selling your own fries. Bidding begins at 50.000 Euro… It’s big business there.
But, they do have good fries. If you want to know my personal favorite of the two… you’ll have to do the tour with me then!
