What is the best alternative to safely cooling foods without a blast chiller?

One of the best alternatives to safely cooling foods without a blast chiller is the use of a food cooling paddle. These are flat, stainless steel paddles that are inserted into hot food and stirred constantly to quickly reduce its temperature. The paddle has a built-in cooling system that effectively transfers heat from the food to a surrounding layer of cold water, which is rapidly circulated by an electric pump. This cooling system is highly effective in cooling down the food quickly, and it also helps prevent the formation of hot spots that can lead to food spoilage. Another alternative method is the use of ice baths, where the food is placed in a container and covered with ice while constantly being stirred. This method cools the food down slower than the paddle, but it is safer than leaving food out to air-cool, which can lead to bacterial growth.
