Cajun cuisine is a style of cooking named for the French-speaking Acadian people deported by the British from Acadia in Canada to what is now called the Acadiana region of Louisiana. Cajun cuisine is sometimes referred to as a 'rustic cuisine', meaning that it is based on locally available ingredients and preparation is relatively simple.
An authentic Cajun meal is usually a three-pot affair, with one pot dedicated to the main dish, one dedicated to steamed rice, special made sausages, or some seafood dish, and the third containing whatever vegetable is plentiful or available. Crawfish, shrimp, and andouille sausage are staple meats used in a variety of dishes.
The aromatic vegetables green bell pepper, onion, and celery are called the holy trinity by Cajun chefs. Cajun food is famous for being very well seasoned which is sometimes misunderstood as spicy. Seasoning is one of the most important parts of Cajun cooking, and that comes from much more than a heavy helping of cayenne pepper. Most dishes begin with a medley of vegetables based on the French mirepoix.
