"Holy Trinity": a blend of green bell peppers, onions, and celery. This mix is used as the foundation for many dishes much like the French mire poix. In fact, this is also sometimes referred to as the "Cajun Mire Poix."
Brown Roux: Unlike a traditional roux which is cooked briefly before the liquid whisked in, brown roux is cooked slowly and carefully until it's a deep chocolate brown. Rather than a thickener, brown roux is more of a flavor base for many Louisiana dishes. Also, brown roux usually uses oil or lard instead of butter.
Blackening: Coating meat with a blend of dry spices and then cooking it over very high heat.
