During stock finishing, what happens to the fat at the surface?

• A. It is skimmed to improve clarity.
• B. It is kept to enrich the stock.
• C. It is stirred back into the stock.
• D. It is discarded.

Answer: (A)

Skimming the surface fat during stock finishing is essential to produce a clear, clean stock. As the stock simmers, fat and impurities rise to the top forming a skim. Removing that layer prevents the stock from becoming greasy and cloudy, helping maintain a bright color and refined flavor. If the fat were kept or stirred back in, it would re-emulsify with the liquid, creating a dull, oily texture and less clarity. Skimming the surface fat is the standard step to finish a stock with a lighter, more professional mouthfeel.
