• Always use the canner on a level, stable surface․
• Ensure the canner is placed far enough from the edge of the stovetop to prevent accidental tipping․
• Never leave the canner unattended while it’s heating or under pressure․
• Avoid using damaged jars or lids as they can compromise the seal and result in food spoilage or unsafe conditions․
• Never overfill jars with food or liquid, leaving at least 1 inch of headspace for proper processing․
• Always use the correct processing times and pressures recommended in the USDA canning guidelines․
• Never attempt to force the lid onto the canner․



• Always vent the canner properly to release steam before applying pressure․
• Never use the canner to cook food other than for canning purposes․
• Keep children and pets away from the canner while it’s in use․
• Use caution when handling hot jars and lids․
• Always wear oven mitts or pot holders when handling hot items․
• Store the canner in a clean, dry place when not in use․

Canning Basics

Pressure canning is a crucial method for preserving low-acid foods like vegetables, meats, poultry, and fish․ It utilizes high temperatures and pressure to destroy harmful bacteria and ensure long-term shelf stability․ Here’s a breakdown of the essential principles of pressure canning⁚

• Understanding Acid Levels⁚ Low-acid foods have a pH level above 4․6, making them susceptible to botulism, a potentially deadly foodborne illness․ Pressure canning is the only safe method for preserving these foods․
• Pressure and Temperature⁚ The pressure inside the canner creates a higher boiling point for water, allowing temperatures to reach 240°F or higher, effectively eliminating harmful bacteria․
• Processing Time⁚ The duration of processing time depends on the specific food being canned, the size of the jars, and the altitude․ USDA canning guidelines provide detailed recommendations for each food type․
• Proper Sealing⁚ A secure seal between the jar lid and the jar is vital to prevent contamination․ The pressure inside the canner creates a vacuum seal, ensuring the food’s safety․
• Cooling and Storage⁚ After processing, allow the jars to cool completely within the canner to prevent breakage․ Once cooled, store the jars in a cool, dark, and dry place for optimal preservation․

Using the Presto 16 Quart Pressure Cooker Canner

The Presto 16 Quart Pressure Cooker Canner is a reliable and versatile tool for home canning․ Before using it, familiarize yourself with the safety precautions and basic canning principles outlined in the manual․ Here’s a step-by-step guide on how to use the canner⁚

• Prepare the Jars and Lids⁚ Wash and sterilize jars and lids according to recommended procedures․ Use fresh lids that haven’t been previously used․
• Prepare the Food⁚ Pack the jars with the chosen food, leaving adequate headspace as per USDA guidelines․ Ensure the food is properly prepared and processed before packing․
• Fill the Canner⁚ Place the canning rack in the bottom of the canner․ Fill the canner with enough water to cover the jars by at least 2 inches․
• Secure the Lid⁚ Place the lid on the canner and tighten the clamp securely․ Ensure the vent pipe is closed․
• Heat and Pressurize⁚ Heat the canner over high heat until steam vents from the vent pipe․ Allow the steam to vent for 10 minutes to purge the air․
• Maintain Pressure⁚ After venting, adjust the pressure regulator to the appropriate level for your altitude․ Monitor the pressure gauge and maintain the correct pressure throughout the processing time․
• Process and Cool⁚ Once the processing time is complete, turn off the heat and allow the canner to cool naturally․ Do not open the canner until the pressure gauge reads zero and the vent pipe stops hissing․

Filling the Canner

Properly filling the canner is crucial for ensuring safe and effective pressure canning․ The canner should be filled with enough water to cover the jars by at least 2 inches․ This ensures that the jars are submerged and heated evenly during processing․

1. Place the Canning Rack⁚ Begin by placing the canning rack on the bottom of the canner․ This rack elevates the jars, allowing water to circulate freely around them․
2. Add Water⁚ Fill the canner with enough hot water to cover the jars by at least 2 inches․ You can use tap water that’s been heated to a rolling boil or water that’s been heated in a separate pot․
3. Add Jars⁚ Carefully lower the filled jars into the canner, ensuring they are upright and not touching each other or the sides of the canner․ The jars should be completely submerged in the water․
4. Check Water Level⁚ After adding the jars, check the water level again․ If necessary, add more hot water to ensure the jars are fully covered․

Heating and Pressurizing

Once the canner is filled with water and jars, it’s time to heat and pressurize the canner to achieve the necessary temperature for safe food preservation․ Follow these steps to ensure proper heating and pressurization⁚

1. Secure the Lid⁚ Make sure the lid is securely fastened to the canner and the vent pipe is in place․ The vent pipe allows steam to escape during the initial heating process;
2. Heat the Canner⁚ Place the canner on a stovetop burner and bring the water to a rolling boil․ This will create steam and begin to pressurize the canner․
3. Monitor Pressure⁚ As the canner heats, the pressure gauge will begin to rise․ It’s important to monitor the gauge closely and adjust the heat as needed to maintain a consistent pressure․
4. Vent for 10 Minutes⁚ Once the pressure gauge reaches the recommended pressure for your recipe (typically 10-15 pounds per square inch), vent the canner for 10 minutes to remove any air trapped inside․ This ensures a consistent pressure during processing․
5. Adjust Pressure⁚ After venting, adjust the pressure regulator to maintain the desired pressure level․ This may require slight adjustments to the heat as the canner stabilizes․

Processing Time

The processing time is crucial for ensuring the safety and quality of your canned goods․ It’s the amount of time the food needs to be heated at a specific pressure to destroy harmful bacteria and enzymes․ The recommended processing time varies depending on the type of food, altitude, and jar size․

1. Consult USDA Guidelines⁚ The United States Department of Agriculture (USDA) provides comprehensive guidelines for processing times for various foods․ Consult their official publications or websites for accurate information․
2. Adjust for Altitude⁚ If you live at a higher altitude, you may need to adjust the processing time․ The USDA provides charts and tables to guide you in making the necessary adjustments․
3. Monitor Pressure⁚ During processing, maintain a consistent pressure level as recommended in the USDA guidelines․ Adjust the heat as needed to ensure the pressure remains stable․
4. Complete Processing⁚ Once the processing time is complete, turn off the heat and allow the canner to cool naturally․ Do not attempt to cool the canner quickly, as this could damage the jars or create a vacuum that could cause the jars to break․

Cooling and Release

After the processing time is complete, it’s essential to cool the canner safely and release the pressure gradually․ This ensures the jars are properly sealed and prevents any potential accidents․ Here’s how to cool and release the pressure in your Presto 16 Quart Pressure Cooker Canner⁚

1. Natural Cooling⁚ Turn off the heat source and allow the canner to cool naturally․ Do not attempt to cool it quickly by running cold water over it or using a fan․ Sudden temperature changes can cause the jars to break․
2. Pressure Release⁚ Once the pressure gauge reaches zero, wait about 10 minutes before releasing the remaining pressure․ This allows the jars to cool slightly, preventing them from being exposed to a sudden temperature change․
3. Vent Release⁚ After the 10-minute wait, carefully release the remaining pressure by slowly lifting the vent weight or turning the vent knob․ Do this in a well-ventilated area, as steam will be released․
4. Remove Jars⁚ Once the pressure is completely released, carefully remove the jars from the canner using tongs or jar lifter․ Place them on a heat-resistant surface and allow them to cool completely․
