Honestly I don't know that word, are you sure it's properly spelled? Because it sounds like diosrted Polish word with English spelling. Did you, by any means, mean "kolacja"?
Also, you might want to know that, that line ("kreska") over the "n" is not an accent, it's a diacritic mark, same as ?, ó, ?, ?, ?, ?, ? and ?.

They sound different than the letters without the marks.
Interesting about the diacritic mark, I'll keep that in mind.
Okay, hope you guys are ready. Here she goes.
Perhaps Kolachi is Americanized. Basically, it is a nut roll, typically with walnuts and maple:

There is one kind of legitimate Kolachi. One. Not any others.
I'm from Northeast Ohio, which has a lot of Eastern European ethnicity and this is regarded as fact. You never say what kind of Kolachi you want because there is only one kind. And like most Polish food in America, they are made by lovely old Babcias. And of course, the quality of the taste is directly proportionate to the flabbiness of the arms that create it.
It's true, I didn't make that up.
Then...I moved to Texas. And much to my horror they have these little bakeries called "Kolache Factories" with an "e" oddly enough, They claim to sell all types of "Kolaches": Sausage and Cheese, Jalepeno and Ham...
Wha......? No!!!!!!!!!!!!!!!!!!!!

You put cheese and meat into bread and that is a sandwich. If you bake it with sauce or something, it become a calzone or stromboli. It is most certainly not a Kolachi (with an "i"). And to make things even more interesting, these wannabe pastries look like danishes. Can't tell you how many arguments I've gotten into about this. I have heard that Kolachis are sometimes considered to be Czech, which may have some truth to it, but I've always known them as Polish
Anyway, was hoping you would give an unequivocal ruling on the authenticity of the Polish Kolachi. I would then print the post out and carry it around with me and starting waving it around when people start talking about what type of freakin' panini (er...Kolach"E") they want. And if they argue, I will say: A Polish person said so...damnit
Bitter Coast out.
