I haven't drank buttermilk since I was a kid (at least 34 or more years ago), but my niece (19) flipped out when see saw me sucking on a lemon at XMas.
Sour cream on strawberries? No problem with that. My 80 yr old Mother is German, I grew up eating all sorts of things. At one point, she got a multi volume set of world cooking books, we got to try all sorts of stuff. Later, I applied this to my taste in music.
