Handle Pressure

Always preserve with safe recipes that are written based on tested USDA-approved methods for home food preservation. When water bath canning, always remember to adjust your timer based on your altitude. Atmospheric pressure is lower at higher altitudes, so water boils at a lower temperature. Therefore, time will need to be adjusted per the altitude you are at. When pressure canning, higher altitudes will require an increase in the pressure. Reference the altitude adjustment charts included in your recipe books.
