If hamburger can be American, then gulasz can be Polish. It's been hundreds of years, at what point am I allowed to call my great-great-great-great-grandma's recipe my culture?

"Jerzynowa" is a funny misspelling. It's Levenshtein distance 1 from two completely different soups.

Oh yeah right, it looks like I invented a new soup and immediately made an orthographic error in its name with this misspelling :p

As for the hamburger - its origin history is quite complicated with its name mainly attributed to its early marketing in USA, so I think that's a bad example for your good point. So skipping that I think there are many dishes that get adopted into the local dishes, getting more popular than in the origin culture, but I don't think gulasz is one of them, as it's one of the most known examples of Hungarian kitchen

Lickmyballs, or polishmyballs? Funny nickname.

I specifically picked an example that's super mega deeply ingrained in American cuisine, because this is the level of how super mega deeply ingrained gulasz is in Polish kitchen. About half of traditional Polish dishes - even the famous schabowy - are more recent inventions than gulasz. You're not going to argue schabowy is actually German and not Polish, are you?

And gulasz is also known as stoofvlees. A beef stew…

And hot dogs are... what exactly?
