Blaming Jefferson is always a safe bet. That wikipedia page also has this :
It is claimed that fries originated in Belgium, and that the ongoing dispute between the French and Belgians about where they were invented is highly contentious, with both countries claiming ownership.
Nothing could be further from the truth, and the source it quotes is of course written by an English author. No one in France doubts that fries are Belgian, because that's Belgian Stereotype #1 (eating fries). #2 is that they're dumb (kind of like the Dutch for Germany).
More on-topic : my favorite food is
Fondue bourguignonne, which doesn't even have an English wikipedia page, what ? And of course the only language it has a page in is Italian, because those guys know food too.
I think "fondue" is how you guys refer to a fondue savoyarde, the one with bread and cheese. Well, replace the cheese with oil (the food kind), and the bread with beef (generally Charolais). Add some Béchamel (and other similar stuff too, but mostly Béchamel) et voilà, you've got the best thing ever.
Oh, and you can have "French" fries on the side. And some vegetables (green beans with onions typically in my family) too, because you know.
