Ideal, I know what you are talking about. People in different regions of the country do make things differently sometimes. A few years ago, I dated a guy from Pennsylvania and we always had disagreements about the "correct" way certain foods should be made. lol
He also had problems with the combination of foods I ate. I'm from Charleston, so shrimp and grits is something we eat for breakfast, lunch, or dinner. He couldn't understand it. No need for me to ever offer him some Frogmore Stew. He just didn't know what he was missing.
However, I think I was right when I told him Krispy Kreme are better than Dunkin Donuts. It just took time for the rest of the country to be introduced.
But, I've never had a corned beef sandwich!
