I'm gonna add a couple that came to mind rocky mountain oysters it is true that you can deep fat fry pretty much anything and it will taste ok(only had them once) after I found out what they were I didn't want anymore.
Also sushi never new raw fish could taste so good tried some for the first time when I went to L.A. then I came back to Manhattan and was v. dissapointed. And now that I think about it I use to get bubble gum ice cream at kreem kup in manhattan when they were open Ice cream is another thing though where you can mix about anything into it and it still tasts pretty good.
