H is for Holy Trinity

The Cajun Holy Trinity or just Holy Trinity is a term used in Cajun and Creole cooking to describe the group of three essential aromatic vegetables: onion, bell pepper and celery. These three items are the base mixture for most recipes such as gumbo, jambalaya, etouffee, sauces, stews and more.

The Term holy Trinity is appropriate in New Orleans culture where Christianity and Catholicism are so prevalent.
Just as the Father, SOn and Holy Spirit are the core of Christianity, Celery, Onion and Bell Pepper are at the core of Cajun Cooking.
