are you joking? they are a european jewish thing (from poland, according to wikipedia).

they only seem to be commercially popular in the usa/canada/uk, but you should be able to find them in any jewish deli/bakery in mainland europe.

Well, origin and source of popularity are two different things. While most yeast-free methods of baking can be traced to Jewish roots, the bagel in it's current, cream-cheese dressed form was made popular (and for most intents "invented") in the US, in much the same way as the minced beef introduced to Hamburg in the 19th century by Russian sailors bears little similarity to the food that made McDonalds successful.

Not to mention the Doner Kebap you get in Germany vs the Turkish original.

You can usually find them in America, I don't know if we invented them though. It looks like they're of Polish Jewish origin.
