Cajun shrimp and grits recipes, like this one made popular by restaurants in New Orleans, are made with Cajun seasoning and bacon, whereas Old Chareston-style grits (also known as South Carolina grits or low country grits) are made without Cajun seasoning and use andouille sausage instead of bacon. Additionally, South Carolina shrimp and grits feature a gravy-like sauce that is thickened with flour, whereas not many Cajun recipes do not.
