Quick Answer
To maintain consistent pressure while canning, use a pressure canner with a weighted gauge and follow the recommended guidelines for water level and heating procedure, ensuring the canner reaches and maintains the required temperature (usually 240°F) for a specified time.
Choosing the Right Pressure Canner
When selecting a pressure canner, consider a model with a weighted gauge, such as the dial gauge or the weighted guage on the Fagor and Presto models. These gauges provide a more accurate reading than the older style J gauge. Make sure to follow the manufacturer’s instructions for calibration and maintenance.
Preparing the Canner
Before use, ensure the pressure canner is clean and free of any debris. Add the recommended amount of water, usually between 2-4 quarts, depending on the model and the type of canning being done. For high-altitude canning, add more water to compensate for the lower boiling point. Close the lid and make sure the canner is properly sealed.
Heating and Pressure Procedure
Follow the recommended heating procedure for your pressure canner, which typically involves heating the canner to 10-15 PSI, then reducing the heat to maintain the pressure. Use a thermometer to ensure the temperature reaches 240°F. For canning low-acid foods like meats and poultry, it’s essential to follow the recommended pressure and temperature guidelines to ensure safety and quality. Regularly check the pressure gauge and adjust the heat as needed to maintain the required pressure.
