I love New Orleans, and Mardi Gras, and the whole Cajun culture (especially Cajun Zyedeco music, but that is another post for another day!).
This is a fun and very rare cookbook. It's called Le Vieux Mardi Gras Des Cajins - Mardi Gras Cook Book and it was written by the St. Thomas More Catholic Church in Eunice, Louisiana (1994). It is chock-full of fabulous Southern and Cajun recipes.
