What is a mixture of onions, carrots, and celery called?

The mixture of onions, carrots, and celery is known as mirepoix. This combination serves as a flavor base in a wide range of dishes, particularly in French cuisine, where it is integral to many soups, stews, and sauces. The blend provides a depth of flavor when sautéed in fat, such as butter or oil, and it is often the first step in the cooking process for dishes that require a rich and aromatic foundation.

Mirepoix is typically used in a ratio of 2 parts onions to 1 part each of carrots and celery, but this can vary based on the specific dish or personal preference. The key here is that mirepoix is essential for building flavors, enhancing the overall taste profile of the dish.

Other options refer to different culinary preparations: sofrito is a mix of aromatic ingredients like herbs, garlic, and tomatoes commonly used in Latin cuisines; roux is a thickening agent made from equal parts flour and fat cooked together; while gazpacho is a chilled soup made with tomatoes, vegetables, and spices. Understanding the unique purpose of mirepoix in cooking helps clarify its significance in culinary practices.
