Two safe methods for cooling stock are

• A. Ice Water Bath and Ice Paddle
• B. Refrigeration while stock is hot
• C. Boiling water bath
• D. Direct contact with ice cubes in the stock

Answer: (C)

Keeping stock safe means quickly lowering its temperature to the safe range to limit bacterial growth. The two tested methods are an ice-water bath and an ice paddle. An ice-water bath surrounds the hot stock with cold water and ice, and constant stirring speeds heat transfer, pulling heat out rapidly without adding liquid to the stock. An ice paddle is a metal implement filled with water or ice that you freeze and then move through the stock to extract heat efficiently, again without diluting the stock. These approaches maximize heat extraction and cooling efficiency. Other options don’t work as well: refrigeration while the stock is still hot risks raising the fridge temperature and slowing overall cooling, which can invite spoilage. Directly adding ice cubes can dilute the stock and cool unevenly, making the process slower and less reliable. Boiling water would not cool the stock; it would keep it hot and delay reaching safe temperatures.
