I am from the southeast US. I don't necessarily believe any of these dishes are unique to my area, but I really enjoy them.
- Grits. Sort of like oatmeal but corn. There are plenty of ways to make it, some make it sweet, some make it savory, some do a little of both. Shrimp and grits is a popular dish, but I think it's more associated with Louisiana specifically.
- Divinity. A very rich, sugary treat. I haven't had many chances to have this, but it's very good. It's the sort of treat I associate with big family dinners on Thanksgiving from family members who "haven't seen [me] since [I] was this big" who have long since passed away.
- Reindeer Mix and Diddly Doos. These are two winter treats my family makes. I don't believe they're local dishes or anything, but because my mom makes them I do consider them cultural. Reindeer Mix is essentially home made Chex Mix you mix a few forms of Chex cereals with other ingredients and drizzle a savory sauce over it and bake it. Tastes best warm. Diddly Doos are basically cheese biscuit/crackers. Think "cheese straw" but shaped in a disk. I think some people call them cheese doodles.
