What american foods are you surprised to hear people outside your country has never tried?

Thanks Giving is something we see all the time. Out of that meal the foods I have tried are Turkey, Mash Potato and Gravy and Apple Pie.

No where ever have I seen Sweet Potato Casserole, Pumpkin Pie, Collard Greens, Yams, I dont even think Cranberry sauce outside of the Jarred stuff is available here.
