This is going to sound strange, but I grew up in NC and absolutely love grits. I used to eat them every day as a kid, and would eat them every day in London if I could. BUT, I've never in my life eaten shrimp and grits. I even lived in SC for a few sad years and still never ate them. Why would anyone put shrimp in grits? The mind boggles.
By the way, my local Tesco used to sell packets of Quaker instant grits in the normal aisle, right next to the oatmeal. I was in heaven but it only lasted a few months.
