I first learned about Cajun flavor when I started eating and making Jambalaya rice. I usually buy it in a box and I would just add meat or seafood into the rice. Coming from a rice-bowl society in Southeast Asia, the concept and taste of Jambalaya rice is still new to me. Since my introduction to this flavor, it opened my eyes further to the diversity of the flavor traditions in Southern United States, specifically Louisiana.
You can say that Cajun flavor found an unexplored territory in my palate. That was my first encounter with Cajun cooking. Then I started making soup Gumbo, which is another Louisiana cuisine but in a Creole tradition. A first, it got me confused about its distinction with Cajun. So I started digging for facts and I found the simplest explanation there is on the web.
It says, the basic difference between Louisiana’s Cajun and Creole cuisines is that the latter (creole) uses tomatoes either fresh, paste or sauce while the former (Cajun) does not.
