A better approach is to cool hot food to room temperature, within 2 hours, by placing it in a shallow container and letting it sit on the counter or using an ice bath to expedite the process. Once cooled, you can safely store it in the refrigerator at a temperature of 4°C (39°F) or below. This careful handling ensures food safety, reduces the risk of foodborne illnesses, and maintains the overall quality of your perishable items.

Can I cool food by placing it in a cold-water bath?

Cooling food quickly and safely is crucial to prevent bacterial growth and maintain nutritional value. One effective method is to submerge food in a cold-water bath, also known as a “cold water shock” or “cold water immersion”. This technique helps to rapidly reduce the food’s temperature, slowing down the growth of microorganisms. To ensure success, choose a cold-water bath with a temperature between 32°F (0°C) and 45°F (7°C), which is below the danger zone for bacterial proliferation. For example, placing cooked poultry in a cold-water bath can lower its internal temperature to a safe 140°F (60°C) within 30 minutes. When using this method, remember to never submerge food in ice or ice-cold water, as this can cause the temperature to drop too quickly, potentially leading to temperature shock or even food poisoning.
