I live in America and am wondering what american candies do they not have in Poland
Twix, mars, snickers, bounty, kit kat are all present but beyond that not much (I haven't lived in the US for a long time so I might be out of date)
Thinking of things that aren't much like things available in Poland...
red hots - the idea of hot and sweet is very not within the Polish conception of the universe
twinkies (not candy but it's mentioned a lot and she might not realize how weird/nasty they are)
fudge (make sure it's well sealed)
As I said I'm out of touch with the current candies so my list might be dated...
