What are effective methods to cool down stock?

Batching stock to 70°F or below using an ice paddle is an effective cooling method because it allows for rapid heat exchange, reducing the temperature of the stock quickly and safely within the critical time frame. This process helps prevent the growth of harmful bacteria that could multiply if the stock remains in the temperature danger zone, which is between 40°F and 140°F.

The use of an ice paddle—essentially a wide, flat tool filled with ice—transfers heat away from the hot stock more efficiently than simply allowing it to cool in a container. Batching ensures that the volume of stock is manageable, allowing for adequate cooling throughout and minimizing the risk of uneven cooling.

This method aligns with food safety guidelines, which emphasize the importance of cooling foods swiftly to maintain their safety and quality. Other methods like ice baths or refrigeration can also promote cooling but may not offer the same level of efficiency and control as combining the ice paddle with the reaching of the designated temperature threshold.
