I'm from Indiana and visiting friends in the Fishkill/Poughkeepsie area (just upstate from NYC). Will drive home soon and want to pack the trunk with some regional foods that are hard to find in Indiana. Right offhand, all I know is that I'll buy a case or two of Tuttorosso tomatoes, which are not available outside the New York area. I could arrange to get a cooler if some chilled transport is required. (The drive is 11 hours.)
Note: I didn't post this in a New York forum, because my concern is home cooking, and also I'm pretty sure most people in the NY area aren't clear about what's unavailable elsewhere. I bet the best responses will come from expat Northeasterners who know what they miss having on hand.
