Mirepoix composition by percentage?

• A. Onion 50%, Carrots 25%, Celery 25%
• B. Onion 60%, Carrot 20%, Celery 20%
• C. Onion 40%, Carrot 30%, Celery 30%
• D. Onion 50%, Carrot 50%, Celery 0%

Answer: (A)

The main idea is that mirepoix is the classic French flavor base made from onion, carrot, and celery in a 2:1:1 ratio by weight, which translates to about 50% onion, 25% carrot, and 25% celery. This balance gives the dish a foundation that’s sweet and aromatic without any one vegetable overpowering the others.

Why this ratio works: onion provides the primary sweetness and aroma, carrot adds a softer sweetness and color, and celery contributes distinctive herbal aroma and a subtle freshness. Together they create a well-rounded base for stocks, soups, and sauces.

If a option omits celery, or shifts the balance away from 2:1:1 (for example, more onion or more of the other vegetables), the result leans toward a different flavor profile and isn’t the traditional mirepoix. The choice that matches 50% onion, 25% carrot, and 25% celery best fits the standard.
