The “holy trinity” in cooking refers to a combination of three vegetables that form the base of many dishes, particularly in Cajun and Creole cuisine. It typically consists of onions, celery, and bell peppers, which are sauted together to create a flavorful foundation for stews, soups, gumbos, and more.
The holy trinity is essential in these dishes as it provides a depth of flavor and aroma. Onions offer a sweet and pungent base, celery adds a subtle earthiness, and bell peppers contribute a vegetal sweetness and vibrant color. Together, these vegetables create a harmonious balance that enhances the overall taste of the dish.
