My mom called this Hungarian mac & cheese. My kids love it. I always use butter and lots of salt and pepper. Sometimes I add poppy seeds too. Definitely a comfort food from my childhood.
We always had this made with shell pasta when I was a child. I have been making it with bowties as well but any fun shape could work! We use light sour cream now and 2% cottage cheese. We tend to use a little less sour cream and a little more cottage cheese. My daughter-in-law was recently in Iraq for a year. She started mixing this for herself in the mess hall as there was almost always some form of pasta and sour cream and cottage cheese available! Soon other soldiers were doing so as well and it became a favorite alternative to mess hall food! It sounds too simple to be good but its really a terrific comfort food!
