What is typically included in a classic mirepoix?

A classic mirepoix is a fundamental mixture used in cooking, particularly in French cuisine, that forms the base flavor for soups, stews, sauces, and many other dishes. The traditional ratio consists of two parts onion, one part carrot, and one part celery.

Carrots add natural sweetness, onions provide depth and foundational flavor, and celery contributes an earthy and aromatic quality. This combination creates a well-rounded flavor base that can enhance the overall taste of the dish being prepared. Mirepoix can vary slightly in preparation and proportion, but the inclusion of carrots, onions, and celery is consistent across most culinary practices.

Options that contain tomatoes, garlic, peppers, or other vegetables do not align with the classic definition of mirepoix. These ingredients might be used for different purposes or in other types of flavor bases, but they do not represent the traditional mirepoix, which is specifically about the trio of carrots, onions, and celery.
