I lived all over growing up.
At home food for me is Southern because my parents grew up there. So, yes, pulled pork BBQ, grits, really fine patty sausage unlike you can get anywhere else, greens, fried chicken, black-eyed peas, fresh tomatoes (also unlike anywhere else) corn.
I have my own favorites from everywhere though.
From Philly: Cheesesteak and these odd little seasonal candies called Irish Potatoes (available for St. Patrick’s Day), soft pretzels.
From New York: real bagels (do not taste the same anywhere else), hot pastrami, cheese slice of pizza (Oh, manna by any other name).
From Maine: lobster, lobster roll (really its own separate food), chowders of all types (clam and haddock) blueberry pancakes, whoopie pies.
From Seattle: Fisher scones with raspberry jam, salmon, coffee, Frango mints.
Dang, I made my mouth water!
