The shrimp and grits are common in lowcountry SC, too (and have made their way out from there). I forget which type of BBQ they have in AL, and am always interested to see what the local variations are. The banana pudding and pecan pie are typical Southern fare I grew up with.My favorite things in Alabama:
BBQ
Shrimp & Grits
Banana Pudding - Must have
Pecan Pie
Crawfish - Must have
Get to Mobile and the Gulf Coast seafood is a good as any you can find. Find an AJ's for the best Grouper ever. You will have to drive over to Pensacola.
As for crawfish, I'm honestly not sure I've ever had any.
