Mirepoix is a flavor base used to flavor stocks. It is typically composed of 2 parts onion, 1 part celery, and 1 part carrots. Which set of options matches this ratio?

• A. 2 parts onion, 1 part celery, 1 part carrots
• B. 1 part onion, 2 parts celery, 1 part carrot
• C. 1 part onion, 1 part celery, 2 parts carrots
• D. 3 parts onion, 1 part celery, 1 part carrot

Answer: (A)

Mirepoix is built on a specific balance: two parts onion to one part celery to one part carrot. This ratio gives a foundation of sweetness from the onions, aromatic notes from the celery, and additional subtle sweetness and color from the carrots without any single vegetable dominating the flavor. When you see two onions, one celery, and one carrot, you’re following the standard proportion exactly, which is why that option is the best match. You can scale the mix up or down by multiplying all parts equally, for example four onions, two celery, two carrots. Other options would shift the balance—more celery, more carrot, or more onion—altering the intended flavor profile of the stock.
