Did anything like the "Freedom Fries" incident happen before?

If you can find a print cite for the term “French toast” to mean ‘bread dipped in egg and fried’ before the 1870’s, I’d like to see it.

Like so many factoids on the web, this one is bankrupt.

Please note that I’m not disputing the probable French custom of frying stale bread in any manner.

Or it could just be because the rules of English usage call for capitalizing adjectives derived from proper nouns. Things pertaining to France are not referred to as “french”, but as “French”.
