Vegetable stock darkening can be achieved by adding which ingredients?

• A. Mirepoix
• B. Tomatoes, garlic, and seasonings
• C. Beef bones
• D. Water only

Answer: (B)

Darkening a vegetable stock comes from using ingredients that contribute pigment and can develop color as they cook. Tomatoes bring a strong natural pigment (lycopene) that deepens the color of the stock as it simmers and reduces, giving a richer, darker hue. Garlic and other seasonings add flavor and can contribute a touch of browning, but they don’t darken the stock as effectively as tomatoes. Mirepoix adds aroma and body and can tint the stock, but without a pigment-rich ingredient like tomatoes, the color won’t reach a deep shade. Beef bones aren’t appropriate for a vegetable stock, and water alone won’t darken the liquid.
