Operating Instructions: Pressure Canning Basics
Proper preparation is key: jars must be ready, filled correctly with appropriate headspace, and the canner needs the correct water level for safe processing.
Preparing Jars and Lids
Before beginning, thoroughly wash jars in hot, soapy water, rinsing completely. Sterilization is crucial; place clean jars on the rack inside the canner, adding enough water to cover them by an inch. Bring to a boil and maintain for 10 minutes at altitudes below 1,000 feet, adding 5 minutes for each additional 1,000 feet.
Keep jars hot until filling. New lids require a 5-minute simmer in hot water to soften the sealing compound – do not boil. Inspect jars for chips or cracks, discarding any damaged ones. Use only lids designed for canning; single-use lids are essential for a proper seal. Properly prepared jars and lids are fundamental to safe and successful home canning.
Filling Jars Correctly
Proper filling is vital for safe canning. Leave the headspace recommended for each food – typically ¼ inch for high-acid foods like fruits and ½ inch for low-acid foods like vegetables and meats. Use a canning funnel to avoid spills and maintain accurate headspace.
Remove air bubbles by gently running a non-metallic spatula or bubble freer along the inside of the jar. Wipe the jar rim with a clean, damp cloth to ensure a good seal. Center the lid on the jar, and apply the band fingertip-tight – do not overtighten. Consistent and accurate filling ensures proper heat penetration and a reliable vacuum seal.
Water Level Requirements
Maintaining the correct water level is crucial for safe pressure canning with your Mirro 22 Qt canner. Always follow the minimum water depth guidelines specified in your recipe or the canner manual – typically, at least 3 inches of water must cover the jars completely.
Insufficient water can cause jars to break or food to spoil. For models with a false bottom, ensure the water level is above the rack. Do not overfill, as this could cause the canner to vent excessively or prevent proper pressure build-up. Always check the water level before locking the lid.
Venting the Canner
Proper venting is a critical step before pressurizing your Mirro 22 Qt canner. After locking the lid securely, allow a steady stream of steam to vent for 10 full minutes. This process removes air from inside the canner, ensuring accurate temperature and pressure during processing.
The steam should be visible and consistent throughout the entire venting period. After 10 minutes, attach the pressure regulator (weight) to the vent pipe. Failure to vent adequately can result in inaccurate processing times and potentially unsafe food. Always vent before each canning session, even if you’ve recently used the canner.
Locking the Lid and Building Pressure
Securely locking the lid is paramount for safe operation of your Mirro 22 Qt canner. Ensure the lid is properly aligned with the canner body and rotate it clockwise until it locks firmly into place. After venting for the required 10 minutes, attach the pressure regulator (weight) to the vent pipe.
Heat the canner on medium-high heat. Monitor the pressure gauge (if equipped) or listen for the regulator to begin rocking gently. Building pressure typically takes several minutes. Maintain the correct pressure – usually 10 PSI – by adjusting the heat as needed throughout the processing time.

Understanding 10 PSI is vital; it’s not about reaching the number instantly, but maintaining it throughout the processing time. The pressure regulator weight controls this, allowing steam to escape when pressure exceeds 10 PSI, and sealing to build pressure when it drops.
Altitude adjustments are critical. At higher elevations, water boils at a lower temperature, requiring increased pressure for safe canning; Consult altitude adjustment charts to determine the correct PSI for your location, as 10 PSI may not be sufficient.
The Role of the Pressure Regulator
The pressure regulator weight, often referred to simply as the ‘weight’, is a crucial component of the Mirro 22 Qt canner. Its primary function is to maintain a consistent 10 PSI (or adjusted PSI for altitude) within the canner during the processing period.
This is achieved through a simple yet effective mechanism: the weight allows excess steam to escape, preventing pressure from building too high. Conversely, when steam production slows, the weight seals the vent pipe, allowing pressure to rise.
A properly functioning weight will gently rock or jiggle as pressure is regulated. If it doesn’t, or if it’s consistently silent, it indicates a problem requiring immediate attention to ensure safe canning practices.
Interpreting the Pressure Gauge (If Applicable)
Some Mirro 22 Qt canners are equipped with a pressure gauge, offering a visual reading of the internal pressure. It’s vital to understand how to accurately interpret this gauge for safe and effective canning. The gauge displays pressure in pounds per square inch (PSI).
Ensure the gauge is clean and functioning correctly before each use. Refer to your recipe to determine the required PSI for your altitude and food type. Maintain the indicated pressure throughout the processing time, adjusting the burner heat as needed.
If the gauge reading is inaccurate, or if the glass is broken, discontinue use and replace the gauge immediately. Relying on a faulty gauge can lead to under-processing, posing a food safety risk.
Adjusting Heat to Maintain Pressure
Maintaining a consistent pressure throughout the canning process is crucial for food safety. After reaching the desired PSI (typically 10 PSI for many foods), adjust the burner heat to stabilize the pressure. Watch the pressure regulator – it should gently rock or jiggle a few times per minute.
If the pressure drops below the target, slightly increase the heat. Conversely, if the pressure rises too high, reduce the heat. Small adjustments are key; avoid drastic changes. Consistent monitoring is essential.
Fluctuations are normal, but prolonged deviations from the target pressure can compromise the seal and safety of your canned goods. Practice makes perfect in mastering heat control.
Timing the Processing Period
Begin timing only after the pressure regulator reaches and maintains the correct PSI (pounds per square inch) for your recipe and altitude. The initial time to build pressure is not included in the processing time. Ensure the regulator is consistently rocking or venting as specified.
Carefully monitor the pressure throughout the entire processing period, making minor heat adjustments as needed to maintain a steady pressure. Deviations can affect food safety.
Once the timed processing is complete, turn off the heat and allow the canner to cool naturally. Do not attempt to speed up the cooling process.
