This is pretty late but I'll post why french fries are called french fries (Learned it last year at school).
About 150-200 years ago the Belgian Fishermen couldn't fish in the winter so they made out of potatoes fishlike potatoes and they baked it, and they liked it, so they began to make them in all kind of shapes.
And then the Frenchmen came and tasted the fries and they liked it to. But they imported it first to England, so that the Englishmen thought(I don't know how to write it) the Frenchmen were the ones who made them and called them french fries.
