Which stock-based sauce is a foundational component in many French sauces and is built from brown stock, mirepoix, and tomato, thickened with roux?

• A. Espagnole
• B. Bechamel
• C. Veloute
• D. Lambert Sauce

Answer: (A)

Recognizing the brown sauce base that serves as a foundation for many French sauces. This sauce is built from brown stock, mirepoix, and tomato, and it’s thickened with roux, which gives it body and a deep, glossy texture. That combination creates Espagnole, the classic brown mother sauce in French cuisine. Its depth comes from the long-simmered brown stock and aromatics, and the roux provides the thickness that helps it coat dishes and act as a starting point for many derivatives, like demi-glace.

Bechamel is a white sauce made with milk and roux, not brown stock. Veloute uses white stock thickened with roux, also not the brown-tomato-mirepoix combination described. Lambert Sauce isn’t part of the traditional group of mother sauces and doesn’t follow this brown stock–tomato–mirepoix–roux pattern. So the sauce described is Espagnole.
