Wow, so surprised to see so many Slovaks crawl out of the woodwork.
My mother is 100% Slovak, and I spent at least half a week during my entire childhood and adolescence with her old-world Slovak family. Whenever my Mom visits from California we'll visit Sak's Ukrainian Village, mainly because it's closeby, or venture out to any myriad of Polish restaurants so she can get her "fix." (She prefers Sak's because the bar and its patrons remind her of the old Sokol.)
I disagree that the exchange student here was probably NOT raised in a food oriented family. From my travels in Slovakia, I found that whether you're getting fed by a family like the one I stayed with in a small town or at a family-operated restaurant, Slovaks, like countless other cultures, are food-oriented, even if the availability of ingredients is limited. In fact, that may make them more food-oriented. Throughout most of its history, Slovakia was primarily an agrarian culture, and evolved into an industrial nation only in the last 50 years or so. Also, it was sealed off as a longtime member of the Communist bloc and subject to their shortages. Thus, most food they have is grown or made locally. There's a huge difference in taste between a freshly-killed chicken and one that's been frozen for three months. There's also a huge difference between fresh vegetables and those served up in a lot of restaurants and between bread that's stale and that which is fresh. We forget how much we (even us chowhounds) sacrifice in quality and freshness as Americans (or at least we're willing to put up with it).
For example, twelve years or so ago, I remember visiting what was the "supermarket" in the small town in Slovakia where I stayed. It was the size of a 7-11, but with its shelves mostly bare, and it sold almost exclusively soda or novelty drinks and candy; but very few things you could make a meal of. I think that says a lot. This experience also mirrors my family's where they didn't starve during the great Depression in part because they raised their own chickens and grew their own vegetables. The store was there for only those things you couldn't raise or make on your own. (My great-grandmother, also rented out rooms for newly arrived Central/Eastern Europeans, was able to communicate adequately with Ukrainians, Poles, and Czechs - that should give you an idea how close their cuisines are as well. She also made bathtub gin for these fellows during Prohibition.)
While I'm not trying to argue that Slovak cuisine (if you can call it that) is superior in any way, imagine if you were raised in a closed-off agro-industrial society, you are not likely to enjoy our notion of fast food (a la Portillo's) or spicy food (like Mexican), which is too unfamiliar. She is also probably homesick, so weaning her away from her culture little by little is probably a good idea. Also, Cathy2's idea to involve her in a making a cross-cultural meal that isn't too shocking to her system might be a good way not only to wean her off her Slovak foods, but also to cure some of her homesickness by providing a little love.
