Placing dry ice in a pressure cooker is not safe and is strongly discouraged. Dry ice, which is solid carbon dioxide, undergoes a process called sublimation when it comes into contact with a warmer environment. As it sublimates, it turns directly from a solid to a gas without passing through the liquid state.
When you put dry ice in a pressure cooker and seal it, pressure builds up rapidly as the dry ice sublimates and releases carbon dioxide gas. This can cause the pressure cooker to explode or burst due to the extreme pressure buildup, leading to serious injuries and damage.
Using dry ice in a pressure cooker is a dangerous practice and should be avoided. If you want to make carbonated fruit, there are safer methods available. One common way is to use a carbonation system designed for food and beverage preparation, which allows you to introduce carbon dioxide gas into a closed container with the fruit. Another option is to make carbonated fruit by dissolving carbon dioxide in a liquid and then immersing the fruit in the carbonated liquid.
Always prioritize safety when experimenting with food and cooking techniques. If you are unsure about a particular method or ingredient, it's essential to do thorough research and seek guidance from experts to prevent accidents and ensure safe cooking practices.
