Using a pressure cookers & canner is a smarter way to deal with food preparation. One functions differently from the other, but both methods increase your efficiency in the kitchen safely and save you both time and money as well.
But first, I want to emphasize that a pressure cooker is not automatically a pressure canner, but a pressure canner can be a pressure cooker. You have to check with the manufacturer first about the functions before purchasing to make sure you are getting the one that will serve your intended purpose.
But then, even if the manufacturer claims that their product can do both, it is important to check that these two parameters are met:
- It should be able to contain at least 4 one-quart containers with the lids on and upright
- It should be equipped with a pressure valve (or at least an option to put one)
Capacity is important in pressure canning because the process can only take place under the right conditions. A bigger pressure pot experiences longer heating up and cooling down times, which ideal for pressure canning. This is not happening with smaller pressure cookers that you can find at home.
A pressure valve is essential for you to check if it achieves the correct pressure to safely can the food. Low acid foods (the ones ideal for canning) are conducive for bacteria growth if not properly handled. Thus, you must be sure in applying the correct methods to defer the risk of food poisoning.
