Step-by-Step Guide to Using a Canning Pressure Cooker
Now that you’re equipped with knowledge about canning and your tools, let’s walk through the step-by-step process of using a canning pressure cooker.
Step 1: Prepare Your Jars
Begin by washing your jars and lids in hot, soapy water, followed by a rinse with fresh water. To ensure the jars are sterilized, you can place them in the canner, fill with water, and bring to a boil for 10 minutes.
Step 2: Fill Your Jars
Using a wide-mouth funnel, carefully fill each jar with your prepared ingredients, leaving the appropriate headspace as specified in your recipe. Headspace is the space between the food and the lid and is critical for safe preservation. Typically, headspace for pressure canning is between 1 and 1.5 inches.
Step 3: Remove Air Bubbles
Use a bubble remover to gently slide around the inner edge of the jar to release any trapped air bubbles. This step is crucial as it ensures that the food is submerged deep in liquid and reduces the chance of spoilage.
Step 4: Wipe the Jar Rims
Using a clean, damp cloth, wipe the rims of the jars to ensure they are free from food residue, which can affect the sealing process.
Step 5: Apply Lids and Bands
Place your sterilized lids on each jar and screw on the bands until they are fingertip tight. Avoid overtightening, as this can prevent the lid from sealing properly.
Step 6: Prepare the Canner
Add a sufficient amount of water to the canner pot—usually around 2 to 3 inches—instead of directly putting the jars in without water. Follow your pressure cooker’s instructions regarding the exact amount. Place the jar rack inside the canner, and gently position your filled jars onto the rack.
Step 7: Close and Lock the Canner
Secure the lid on your pressure cooker and ensure that it is tightly locked according to the manufacturer’s instructions. It’s essential to ensure the sealing ring is seated correctly to prevent steam from escaping.
Step 8: Heat the Canner
Turn on the heat to medium-high until steam begins to escape from the vent pipe. Allow it to vent for about 10 minutes. This step is vital, as it releases any trapped air that may affect the pressure inside.
Step 9: Build Pressure
After venting, apply the weight or close the vent (if your model has a locked lid). Continue heating until the pressure gauge reaches the recommended pressure level for the type of food you are canning, usually measured in pounds of pressure (PSI).
Step 10: Process the Jars
Once the desired pressure is reached, begin your processing time according to your recipe. Monitor the pressure gauge throughout the process to ensure it remains consistent. Adjust the heat as necessary.
Step 11: Release the Pressure
After the processing time is complete, turn off the heat and allow the pressure to drop naturally. Never force open the canner, as this could result in serious injury. Wait until the pressure gauge returns to zero and the safety lock has released.
Step 12: Remove the Jars
Using a jar lifter, carefully remove each jar from the canner and place it on a clean towel or cooling rack. It’s crucial to leave space between jars for thorough cooling.
Step 13: Check Seals
After about 12 to 24 hours, check the seals on each jar. Press the center of the lid; if it doesn’t pop back, the jar has sealed correctly. If any jars are not sealed, refrigerate them and use them within a few days.
Storage and Use of Canned Goods
Proper storage of your canned goods is just as important as the canning process itself. Here are some tips:
1. Store in a Cool, Dark Place
Store your sealed jars in a cool, dark area, free from temperature fluctuations, as light and heat can degrade the quality of the food over time.
2. Label Your Jars
Clearly label each jar with the contents and date of canning to make organization and future cooking easier.
