If you would like to press the can and cook in one device, this is a great choice. Comes with a dial for accurate monitoring of internal pressure, which is important in pressure canning and high-altitude canning. This can is made of aluminum for even heating and can also be used as a water bath can. It can also be used as a large-capacity pressure cooker. However, since it is aluminum, you should avoid using it for acidic foods like tomatoes. Includes a stand and holds up to seven 1-liter glasses or two layers of 10-pint glasses. In his test batches, our reviewer found this 23-quart stovetop pot to run like clockwork. The locking cover was solid and secure the size was perfect for pressure canning quart jars of baked beans and turning a bumper crop of rhubarb into 13 12oz sauce jars at once with the dose of water bath. Just be aware that you’ll probably have to bring water in a container instead of putting the container in the sink because it didn’t fit.
