Purists insist that a “kolache” with sausage inside is actually a klobosniky. And strictly speaking, it is not Czech in origin, as is the kolache. It is a native Texan. Word has it the klobosniky was invented in West, Texas (which, ironically, is not in west Texas) at the Village Bakery in 1953.
If you are not from Texas, you don’t care. If you are from Texas, you probably still don’t care. Frankly, I’m not sure how much I care. I just like saying klobosniky.
