What role does mirepoix play in stock?

• A. Provides a flavor base
• B. Thickens the stock
• C. Adds color only
• D. Is used as garnish

Answer: (A)

Mirepoix acts as the flavor base for stock. By gently sweating onions, carrots, and celery at the start, you release aromatics and sugars that infuse into the liquid as it simmers, creating the foundational savory backbone of the stock. This flavor base supports the bones and other seasonings, giving the finished stock depth and balance. It isn’t meant to thicken the liquid, and it doesn’t serve as garnish or primarily add color. For white stock you sweat the mirepoix to keep it light; for brown stock you may roast it to deepen color, but the purpose remains to build flavor from the start.
